When users aren't able to access websites on your server -- are you able to log into Virtualmin, or access SSH?

If possible, what I'd suggest doing is logging in via SSH, and review what's going on at the time. You could run "uptime" to see what the current load on your server is, and "top" to see what's consuming the most resources.

You could also review the various log files in /var/log, and the end of your "dmesg" output to see if any kernel errors are showing up there.

i did pretty much everything

i am not very good at linux

if i can send you ssh access by email can you see

Please let me know because customer is not happy since we change the cpanel to virtualmin

i am using virtualmin for almost 4 yrs but this server is giving me hard time

plz help

here is apache log

I don't see any errors in your Apache log that would explain why it's completely unavailable for long periods of time.

It can be difficult to determine what's wrong when the problem isn't currently occurring though, you may need to look at while the problem is happening.

The one thing you could try now though is to run this command -- what output do you get:

dmesg | tail -10

However, next time the problem happens, if you could log in over SSH and run these commands, that may assist in finding the problem:

  1. uptime

  2. ps auxw

  3. mailq | tail

  4. dmesg | tail
