Support team encountered a similar problem. FDS and NFS (for /home) was on the same machine. A nightly cron doing rsync/tar of the /home caused 'Too many FDS' issue on the FDS. service restart did not help either. This was on RHEL4. The support team decided restart the machine after the rsync/tar. -Satish. > > I do see on the web past posts to this list regarding this error, I am > currently looking through them.
