We are experiencing frequent hangs in slapd. Once hung we usualy cannot continue
to
connect until we kill -9 the slapd process and restart it. The directory is used
for 2 applications as user eDir and we are using it in production over 1 month -
we have noted the busier the directory becomes the more often it hangs (now
twice per week).
We have installed identical configurations on 3 environments, each has only one
single server (no replication). There are 30k entries in the directory
(production).
We are running:
RHEL 5.7 x64 (VMWare with NFS mountpoints)
OpenLDAP 2.4.32
Berkeley DB 4.8.30 (4.7.25)
We were starting with DB 4.8.30, after downgrade to version 4.7.25 (according to
ITS#7378 -
https://www.openldap.org/its/index.cgi/Incoming?id=7378;selectid=7378)
we are facing the same issue.
Note that BDB 4.7.25 is known to self-deadlock if you haven't applied all of
the patches.
