For some reason (I think some eth0 network problem) my server is sometimes not accessible anymore for some hrs! (it does fix itself (sometimes))
1st I thought that it was some programe running on a cron job, but now (with help of Munin) I think I found the problem.
When the server is not accessible anymore Munin is logging eth0 errors (see image)
This is how eth0 looks normal
The server is using Fedora RC4 with ISPconfig, and the Firewall that comes with ISPconfig.
Anyone here who might know what could cause this eth0 error, and how I can fix it?
