Issue:
slapd keeps crashing about twice a day on multiple servers. I updated the kernel and openldap but still see the problem. Anyone point me in the right direction?
Log:

Hi,

A core dump or other means of providing a trace is necessary to say anything about that.
But jsut as a wild guess from what I experienced with the combination of these software versions:
Is there any chance you are logging to a flaky syslog server?
Cheers, Nik
Enable core dumps and examine what crashes.

I was able to get a core dump of slapd. It says I'm missing one module (libtool-ltdl) but here is what gets reported.
Core was generated by `/usr/sbin/slapd -h ldap:/// ldapi:/// -u ldap'.
Program terminated with signal 11, Segmentation fault.

It seems all was fine up until about a week ago. Then my replicas started dropping off 1-3 times a day.
Ideas?

Have you tried 2.4.40? There were some overlay interaction fixes involving the chain code (ITS#7930) in that release.
