Re: How to raise the open file descriptor limit for slapd?

[Robert Petkus <rpetkus@bnl.gov>]

I was able to get past the fd limit on Linux.  Aside from the 
/etc/security/limits.conf mod:
*               soft    nofile          4096
*               hard    nofile         4096

You need to add to /etc/pam.d/other
session    required   pam_limits.so

Then restart your slapd process.

Cheers,
Robert
