(ITS#5332) multimaster replication crash
Full_Name: Marcel Ritter
Version: HEAD
OS: Linux (openSUSE 10.3)
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (131.188.78.179)
When using multimaster replication slapd dies (on x86_64).
I've used the scripts/test050-syncrepl-multimaster with one simple
modification: I added one ldapadd command at the end of the script,
trying to add some 20000 entries.
With this modification it doesn't take long, till one of the slapds
gets a SIGSEGV:
Continuing.
