slapd replication master crash after 90000 inserts and slave never crash (ITS#2804)
Full_Name: Alexandre LABICHE
Version: 2.1.22/2.1.23
OS: HPUX11
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (193.252.217.92)
IF I insert more than 50000 entries the slapd replication master always crashed
while it never happened on slave slapd.
I exeuted this test more than 20 times with differents parameters . I never
reach my 130.000 inserts in one shot without crash the master slapd.
Here is this analysis of the core dump with openldap-2.1.22.
IF you need more it's easy for me to reproduce this crash
Openldap 2.1.22 or 2.1.23 bdb 4.1.25+patch openssl 0.9.7c
