Hi all,

my slapd (@(#) $OpenLDAP: slapd 2.4.44 (Feb 9 2017 13:38:13) $) has developed a tendency to become unresponsive for 10-30 minutes at a time.

I run it with -dStats,Sync which gets me a fair amount of debugging info. This I pipe thru multilog to get the timestamps below.

Why are you using -d? This prevents slapd from forking. It is better to set the loglevel to be stats+sync, and push out data to syslog.

You need to determine why tasks are not finishing and instead are remaining unfinished. What databse backend are you using? I would note that it would appear that you have clients disconnecting w/o waiting for the server to respond (thus the no connection messages).
