Fedora directory users - Jun 2006 - File descriptor problem

I may be missing something obvious, but I''ve got a couple Red Hat EL4
servers running FDS 1.0.2, and I keep getting the dreaded "Not listening
for new connections - too many fds open" error.

I''ve looked at all the install and how-to guides, and have the
following
set up:

/etc/security/limits.conf:

*       soft    nofile  104851
*       hard    nofile  104851

/etc/sysctl.conf:

fs.file-max = 131072

/etc/profile:

ulimit -n 131072

/etc/pam.d/login:

session required /lib/security/pam_limits.so


Still, as soon as FDS hits 1024 FDs open, everything blows up.

What have I missed?  I''ve also added a "ulimit -n 131072" to
the top of
the server''s init script, but no dice.

Hello Patrick.  Check nsslapd-descriptors and nsslapd-conntablesize in 
dse.ldif.  If the latter isn''t present it''ll be equal to
either
getdtablesize() (which is RLIMIT_NOFILE on Linux I think) or 
nsslapd-descriptors, whichever is lower.  nsslapd-descriptors sets the 
soft limit on the ns-slapd process, and nsslapd-conntablesize sets how 
many of the descriptors to use for incoming connections.

Thanks -- nsslapd-maxdescriptors was set right at the point I''m seeing
things break, so I increased it.  Things seem to have been working fine
since then.
