Hello and thank you very much for responding. I do not understand what you mean
by "editing the config (in the database directory). Do you mean by that the
postgresql.conf file? Well, this file is proper set and has been, the
installation has worked well once until May the 26th. I try out to figure out
what happened to CURRENT that time.

In the meanwhile, I tried to rebuild CURRENT from scratch with
WITHOUT_OPENSSL_KTLS set, avoiding any CPU optimization during compilation of
world and postgresql - but without any effect. The pain is, that two boxes
ofthe same CPU arch affected the same way, no matter what I do.
