What if linux servers can't view processes with top and ps? In response to this problem, today's small editor summarizes this article about process troubleshooting, hoping to help more friends who want to solve this problem find a simpler and easier way.
Problem: The server load is very high, top and ps cannot view the process, there are abnormal task plans, but the process cannot be found
Troubleshooting also found the following exception mapping added to/etc/hosts
Guess mining, but no process eventually verified to be/etc/ld.so.preload set hidden process
Attempts to delete or edit this file directly are invalid, and finally try echo "">/etc/ld.so.preload can be entered normally
Then check to see the specific process
OK! It's easy to check if you can see the progress.
When troubleshooting this problem, it is mainly stuck in the hidden process and cannot be further verified and analyzed. As long as the hidden process is handled, it is good to troubleshoot and handle it.
Problem extension: unhide can be installed to view hidden processes
Installation:
Ubuntu or Debian distributions: sudo apt-get install unhide
CentOS/RHEL:yum install unhide
Execution: unhide proc View hidden process
The above is linux server can not use top and ps to view the process of the solution, after reading whether there is any harvest? If you want to know more about it, welcome to pay attention to industry information!
