Fedora directory users - Feb 2007 - error when restarting FDS

Hello,

This night, FDS (1.0.2) refused to start after backup. I found this in
the logs :

[06/Feb/2007:22:04:39 +0100] - slapd stopped.
        Fedora-Directory/1.0.2 B2006.060.1951
        host:389 (/opt/fedora-ds/slapd-supann)

[06/Feb/2007:22:04:51 +0100] dse - The entry cn=config in file
/opt/fedora-ds/slapd-supann/config/dse.ldif is invalid, error code 53
(DSA is unwilling to perform) - nsslapd-maxdescriptors: invalid value
"65536", maximum file descriptors must range from 1 to 1024 (the
current process limit)
[06/Feb/2007:22:04:51 +0100] dse - Could not load config file [dse.ldif]
[06/Feb/2007:22:04:51 +0100] dse - Please edit the file to correct the
reported problems and then restart the server.
        Fedora-Directory/1.0.2 B2006.060.1951
        host:636 (/opt/fedora-ds/slapd-supann)

[07/Feb/2007:08:50:20 +0100] - Fedora-Directory/1.0.2 B2006.060.1951 starting up

Indeed, I checked my system and found :

 [root@host logs]# cat /proc/sys/fs/file-max
 65536

Which seems correct if I follow this page :
http://directory.fedora.redhat.com/wiki/Performance_Tuning#Linux

However, fds started without any problem some time later.

Any Idea about what I should do about this pb ?
Thanks in advance,

How are you settigng your file descriptor limits, and how does the
backup run?  Chances are that when the server is restarted after the
backup, they are not set correctly. I''m going to take a wild guess that
it runs out of cron with an environment that''s not set with the right
number.

Try checking the limit by running "ulimit -n".

Thanks for your answers,

To reply the first mail, "ulimit -n" returns 1024.

I run my backup with a script called by bacula (which runs with root
privileges).
Here''s the content of the script :

#!/bin/sh
echo "stopping fedora directory server"
/etc/init.d/fds stop
echo "rsyncing"
/usr/bin/rsync -a --delete /opt/fedora-ds /opt/fedora-ds.rsync
sleep 10
echo "starting fedora directory server"
/etc/init.d/fds start

Do you know what command I should add to this script to set up the
environment correctly ?

Thanks in advance,

Modify /etc/init.d/fds, and add "ulimit -n 65536" there.
