Wordpress web server & WHM stops responding

cp_noob
I run a website that has 18-20.000 users each month. The last year the site has gone down quite a few times, although I have been able to go into cPanel/Performance/Server Management/Reboot. I was not able to go into WHM - I don't quite know the difference between the two clients. My site runs a few plugins, including an automated backup, and a WHM backup every day. Together with a friend, who knows a little about networking (mostly Windows type) we went through the Apache log, and a few other logs without finding anything particular. I have also set up Munin, but I don't see any special peaks that might reveal the problem. Today I googled my way to check the chkservd.log
which was 128 Mbyte large. I found the log instance just as the services started to fail, and the instance after it had been rebooted. Does any of this make any sense? Are there anything there that might indicate where the problem lies? My site runs on its own VPS. I will be more than happy to find other logs with some guidance. I can supply screenshots of Munin, if it helps. EDIT: here is the Munin printout.

    Hey there! I'm sorry to hear you're having issues with the machine. The WHM access controls things that affect the entire server. You can create new accounts, edit the MySQL database version, make edits to the Apache and PHP packages that are installed, and other things that will affect all the user accounts on the system. The cPanel user login interface is limited to changes for just that one domain, such as creating databases, email accounts, and FTP users. The chkservd log is what shows when a service was restarted automatically by cPanel monitoring, but it will usually not provide any clues as to why the service failed. If you are seeing problems with the Apache service it would be best to check the Apache logs at /etc/apache2/logs/error_log, looking for timestamps that are in close proximity to the restarts you're seeing in chkservd. If you're having difficulty tracking down details on the service failures our support team is always happy to help.

    Thank you. I chatted with the host support, and they asked me to increase the cPanel memory limit, which I did. I will open a ticket here if it is unsuccessful.

    I did increase the memory limit to 256 MB, but it still crashed. Afterwards, I have removed the last plugin I installed, and the server has not crashed since I did that, so I believe I have found the solution.

    Great! Whenever there are new issues it's always a good idea to try undoing previous work to see if that changes the behavior in any way, but I'm glad you were able to get that resolved.
