Ethereum node server stuck

1. Hardware failure or insufficient heat dissipation
of course, it can also be a virus. Try to kill the virus, or reload the system. General virus without disk is more likely

2. When the load is high, apply to change the web server or increase the memory, or restart the web service every certain time

3. Hello, I just visited the card. If you want to find out the culprit, open the running box on the server, enter CMD, then enter again, and then enter iisapp - A to find out the program that charges traffic to drag the network speed

4. 1. Virus infection: general performance, initially able to run normally, one day suddenly slow down, work efficiency dropped sharply, frequent crash. At this time, the first comprehensive inspection, antivirus, to determine whether the machine has been infected with the virus
2. Some software programming is not standardized, so it can not be loaded and run in the first place, but should be run in the last place, otherwise it will cause confusion of system management. The beta software is not stable in some way, which may cause the system to fail to start after use, so it is better to use less
3. In the case of small memory, running applications that occupy a large amount of memory is prone to crash. It is suggested that the files in use should be saved in time when running these programs
5. Software conflict or incompatibility: before installing a certain software, the system works normally. When the system does not work normally after installation, the problem must be caused by the software. Different software sometimes have conflicts and incompatibilities when running, or anti-virus software has a small bug. When it is installed, it will be unable to shut down, the system starts slowly, and the blue screen crashes. At this time, just close or uninstall the software
6. Incompatibility of software and hardware: 3D software and some special software can't be started or even installed normally on some microcomputers, which may cause problems in software and hardware compatibility
7. Do not turn off the power when the application software is not finished normally, otherwise the system files will be damaged or lost, causing automatic startup or running crash. For win 98 / 2000 / NT and other systems, this is very important
8. When unloading the software, do not delete the shared files, because some shared files may be used by the system or other programs.
once these files are deleted, the application software will not start and crash, or the system will crash
9. The host configuration is too low or the loaded programs are too large and too many: at this time, the system resources are too few, and the crash phenomenon will also occur. In this case, you can select & quot; my computer '-'properties' -' Users specify the virtual memory settings themselves, Increase the virtual memory of the system to twice or more of the physical memory. The main solution is to choose the appropriate application software according to the configuration of the machine
Hardware inced crash
1. Poor heat dissipation: the heat generated by the power supply and CPU in the work, and the poor heat dissipation of the power supply will cause crash. The heat dissipation of the CPU is related to the stability of the computer operation, and it is also the "disaster area" caused by overheating
2. Improper movement: if the computer is subject to large vibration ring movement, the internal components of the machine will be loose, resulting in poor contact and computer crash
3. Loose memory mole, false soldering, quality problem of memory chip itself or poor compatibility with motherboard will cause system crash. At this time, you need to remove the contact fault first. If there is a quality problem with the memory mole, you need to replace it
4. Hard disk failure: too many operating systems are installed on the same hard disk, the hard disk is aging, and it is not used properly (causing bad channels and bad sectors), so the machine is prone to crash when it is running. Special tool software can be used for troubleshooting. If the damage is serious, the hard disk can only be replaced
5. Poor quality of hardware or fake, parallel: in the assembly machine, if poor quality boards, memory, or even counterfeit motherboards and marked CPU, memory and other parts are used, the machine will be very unstable and prone to crash
tip: when you can't find out the problem, it's better to consider whether the JS goods are used
6. Overclocking of CPU, display card and other accessories: after overclocking, the performance of CPU and other components will be very unstable, and there are great hidden dangers: it may cause crash, or it may cause the complete scrapping of CPU, memory and hard disk
in addition, if the frequency is too high, the temperature will rise too much, and it will cause restart or crash ring startup or operation. The solution: avoid overclocking
7. Unstable power supply: if conditions permit, it is better to provide a regulated power supply to avoid voltage instability causing crash. If UPS can be installed, the computer can be buffered after power failure to increase the safety factor
8. Poor heat dissipation in the chassis: too much st in the chassis adheres to the surface of CPU, chip and fan, which will lead to poor heat dissipation or poor contact of these components; In addition, it is easy to cause short circuit of printed circuit board in humid environment. Both cases can cause a crash. If there is too much st in the floppy drive head or optical drive laser head, it will lead to reading and writing errors, and also cause crash
9. Poor contact of the data line connected with the peripheral: when the data line between the peripheral and the host is loose, it may also cause data interruption or error in the transmission process, and also cause the machine to crash irregularly
10. Interference: many household appliances, especially variable frequency air conditioners, washing machines, inction cookers, will radiate a lot of electromagnetic waves when they are working. If the computer is nearby, if there is an inexplicable crash or blue screen. At this time, it's better to change the computer to another place
11. Unstable mains voltage: generally, the computer can work normally when the mains voltage is between 180V and 240V. When the voltage is lower than 180V, the output voltage of switching power supply is too low or protected, and the host is easy to restart or shut down automatically; When the voltage is higher than 240V, e to the discrete components of the circuit, the power supply may not be protected at this time, and the secondary power output may be high, which will also cause the crash phenomenon
crash caused by operation:
1. During checking the hard disk with antivirus software, do not run other applications to prevent system crash
2. Network problems: when surfing the Internet, too many browsing windows will be opened at one time, which will lead to resource shortage and crash. Now the popular online games such as Lianzhong, Chuanqi, etc., if the network is not normal, there will also be a crash phenomenon in the process of communication with the server. Some performance in the process of online crash, some performance for offline crash
3. When performing disk defragmentation, do not run large application software, otherwise it will cause a crash.

5. Ha ha
if the FPS is very low, it means that the graphics card of the computer is too low
replacement is recommended
the game is to turn off some useless programs.

6. First, check whether the system log has relevant information, and then observe the operation of the system process after power on to find the abnormal process for further processing.

7. It's not the machine. The problem with the machine is to pop up the wrong prompt directly or you can't get in directly. That's your fwq card.

8. Let's talk about the details, such as what system is the client, what system is the server, what resources you want to access on the server, how to access them, network connection status, etc. If you don't make clear the background of the problem, others can't make a judgment.

9. According to your abnormal traffic, you need to analyze where the abnormal is, whether the traffic is too large or attacked! If the traffic is not really too large, it is necessary to analyze whether it is the program problem or the server is attacked. Not only the program problem will lead to the website not running normally, but also the performance and security of the server itself are equally important
it is estimated that your website is targeted by marketing software, and those members are registered by the registration machine. The solution is to optimize the program and database to increase the security of the website!
