Hi,
I am running a 4-way multi-master configuration with a number of slaves
in remote locations. I am currently running openldap 2.4.33 on top of
CentOS 6.3 (I built 2.4.33 from a modified base centos 6 spec file). I
was originally running the centos base openldap 2.4.23 using N-way
multimaster using the syncrepl configuration but I was having problems
with the masters and slaves staying in perfect sync--other than this
2.4.23 was running stably since last spring. I'll try to be brief in what
has happened since Feb 1.
Did you build openldap with debugging symbols? (-g)
Did you disable optimization? (-O0)
If so, I would advise submitting an ITS, with a full backtrace from gdb:
<http://www.openldap.org/faq/data/cache/59.html>
Oh, also make sure when make install is run, you don't strip the binaries
of the debug symbols (make install STRIP="")
I would also warn against using the centos spec file, as it links to NSS
instead of OpenSSL. You probably want to look at

Quanah,
I re-compiled 2.4.33 using the openssl libraries on Friday and have
installed the updated packages on my four master servers. I have not
experienced a single deadlock since then. The slaves have not been
upgraded yet--they are still running the centos stock 2.4.23 distribution.
The only issue that I still have is one or more threads running at full
throttle and utilizing 100% CPU. But this is a different issue and I'll
start a new thread on this when I get a chance to look at this more.
Thanks,
Bob
