LinuxCN manages the site of www.mu20.com.
One day,webmaster of www.m20.com called to LinuxCN that his server is down.
Telnet to the server,we found a large mount of process of httpd and mysqld used more than 60% Memory.
At last,we found that Access_log of www.mu20.com was more than 90MB.I advised to backup its access_log.
We were surprised that CPU rate & RAM rate of both httpd and mysqld went down.
Which relations between mysqld's CPU/RAM rate and filesize of access_log?
