File table overflow is that you have lot of open files on the system.

1.To fix it temporarily you need to close down the unrequired process which can reduce the number of open files.

2.A permanent fix would be to increase the kernel parameter "nfile"

Increase the parameter nfile.Rebuild the kernel and reboot

That should resolve the problem

Thanks
