test050-syncrepl-multimaster failures

[Rein Tollevik <rein@OpenLDAP.org>]

Like others have reported, I have seen failures with this test after 
upgrading to the recent RE_24.  I have only seen it when running the 
test on a multi-cpu linux system tough, it works find on a single-cpu 
solaris.

When it fails it is always syncrepl in the two first servers that fails 
to bind to the third.  In the logs they complains repeatedly like:

slap_client_connect: URI=ldap://localhost:9013/ DN="cn=config" 
ldap_sasl_bind_s failed (-5)

I.e, the bind timed out.  Server3 logs the bind request, but first after 
the unbind that follows..  Modifying the source with some more debug 
output that prints the time it shows that the bind request is sent and 
times out (after 3 seconds) before server3 logs accept of the 
connection.  Some race condition that kicks in if two servers tries to 
connect and bind at the same time?  Btw, I've only tested with back-bdb.

Well, that's how far I've had time to look at it.  I have plenty of logs 
available if anyone care to look at them.
