Hello,
I have switched to slapd 2.4.18 (last release) and the problem still 
pesist. I have made the requested debug session.

The relevant log file could be found here:
http://purgatory.spnet.net/~karavelov/log

The gdb session is here:
http://purgatory.spnet.net/~karavelov/debug

The configuration file is here:
http://purgatory.spnet.net/~karavelov/slapd.conf.clean

I have tried without pcacheValidate and pcachePosition options without 
any difference.

Thanks in advance
Luben
