I have a virtual dedicated server with 512MB RAM and 2GB Bursted RAM.
When my website gets busy, the server crashes and I have to restart the server to get my site back online. However, this is only temporary and happens again every few hours.
I contacted my host’s support department who said it was a memory problem. I checked the “top” command in SSH, and saw that mysql was using the most memory.
I think it maybe something to do with my my.cnf file configuration. Can someone please take a look: This is the file.
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
max_connections=700
max_user_connections=500

Any help will be greatly appreciated.
Thanks
