Re: ldap deadlock?

I'm looking for ideas here. ldap seems to deadlock once in a while
whereby it continues to accept connections as noted in the log file
but it does not return anything to the query, the query just hangs.There have been no deadlocks reported in OpenLDAP 2.2 after 2.2.20. More
likely you had an unclean shutdown and restarted without running
db_recover, so you have stale locks in the environment. You should
upgrade to 2.3 which does recovery automatically.
It's openldap 2.2.28 using Berkley db 4.2.52 as the backend on a SuSE
9.3 platform. All patches are up to snuff on the OS side.
I'm hoping for pointers to help see what might be going on.
As of today I started running db_deadlock in the background wit the -a
y option to see if that helps.
This deadlocking is getting people up in arms here because it is
disrupting authentication for the whole campus and I guess I can't
