Two many open files? You server must have been busy realy heavily! You
must increase the open files (and inodes and memory pages) limits in
/etc/rc.d/rc.local (for example) by puttind the following lines there:
# increase limit of open files
nr=16384
expr $nr \* 4 > /proc/sys/fs/inode-max
echo $nr > /proc/sys/fs/file-max
# increase size of memory pages reserved for kernel
echo "1024 2048 3072" > /proc/sys/vm/freepages
Good luck
