Which OpenLDAP version is this?
Also note that RedHat heavily patches OpenLDAP and links it against libnss. You should therefore also open a ticket for RHEL.
Getting segaults every 6 hours or so when I let QA on system and generate some typical user load.
All 32 threads halt; ldapsearch stops responding.
Do you have 8 CPU cores?
Typically no logs; last one dropped this:
ie:
Sep 18 07:47:58 maryann2 kernel: slapd[53754]: segfault at 7f3083ffff98 ip 00007f3104cc3532 sp 00007f30a5ff9660 error 6 in libc-2.12.so [7f3104c4a000+18b000]
Should i just sledgehammer a yum update and get off centos 6.5?
The openldap-technical is not a RedHat forum. But being in your position I'd upgrade within the RHEL 6.x series first.
Also consider using the LTB project's OpenLDAP RPMs. Those are linked to OpenSSL libs and are more close to upstream OpenLDAP releases.
