hi, my website got "out of memory" error
but when I use top command to see:
no Swap, no buffer.

The result looks fine.

Anyone has clue on track the memory usage?

Something is messed up on your server. You shouldnt have that many mysql processes. I would start looking through log files to see what is going on. Also turn on apache extended status so that you can view the traffic on apache.
 
Might be a php out of memory problem. Check the php.ini file.
