Hi,

The Openldap backend "ldap" slapd crashing under heavy load. Tested with 2.4.26 and also 2.4.40. We get an segfault: Jun 18 00:00:36 serverxx1 kernel: [9079587.309374] slapd[6193]: segfault at 40 ip 00007f184cf6b2c6 sp 00007f1838ff85c0 error 4 in slapd[7f184cdda000+26c000] Jun 18 09:40:12 serverxx1 kernel: [9114294.985888] slapd[10309]: segfault at 40 ip 00007f3b31f492c6 sp 00007f3b1f7f55c0 error 4 in slapd[7f3b31db8000+26c000] Jun 18 12:38:29 serverxx1 kernel: [9124971.271300] slapd[15868]: segfault 4 40 ip 00007fc1555512c6 sp 00007fc141ffa5c0 error 4 in slapd[7fc1553c0000+26c000]

We can't provide a core dump of the slapd due to confidentially restrictions.

Then we cannot help you.

I suggest you test with the 2.4.41 release candidate and see if the same crash still occurs.
