Ok, the situation is more advanced than just that. I now have the
"sorting" process running while there is high cpu-only load and that
doesn't trigger the problem, so it seems to be that I have to have
"large merging, high cpu-load and lots of networktraffic on the NIC
(10GbitE)" before I encounter the prooblem.

Is there anything I can do to get a trace or other information about
what's holding the "login" process back the next time I get into this
situation?

Thanks
