100 Mb error_log file

[SecondSight]

Hello ! :)

I've just had my server transfered and many files were missing. So, now I have a 100 Mb error_log file...

What should I do then ?

If I rename it, I suppose the server will create a new one and it will be ok ?
How can I fix a size limit to the error_log files ?

I'm using Centos 5 + CPanel.

Thank you ! :)
