Hi,
In our 1 Master - several slaves environment master slapd sometimes stucks in such condition that it takes minutes to get replay to simple queries with no visible resource consumption on both: the slapd process itself and the linux it is running on.
Restarting slapd helps for several days. Today I have not been able to restart it without kill -9 because of:
slapd shutdown: waiting for 12 operations/tasks to finish
Waited 5 minutes with no luck, kill -9, start.
slapd: 2.4.28 OS: Ubuntu 12.04.2 LTS
I'm Ok with "try latest version", but it would be nice to have some pointers (maybe bug in this version or error in configuration).
I would definitely say upgrade to 2.4.38. One thing that particularly stands out from the Changes file:
OpenLDAP 2.4.32 Release (2012/07/31) Fixed slapd-bdb/hdb cache hang under high load (ITS#7222)
Generally, I would suggest getting a full gdb backtrace and looking at the output of db_stat -C A and db_stat -c when it is in this state, if it occurs again after running a current release.
Thanks.
