Kernel 4.1.15-8-default Its running a minimal system with postgresql 9.4 from Repo server:database:postgresql It has two CIFS mounted remote filessystems. I have 4 VM-Hosts. All updated from 13.2 to Leap. With 13.2 it running fine many years without any problem! Host with label "PGSQL01" was Master-Clone for others Hosts (VMs) befor updating. This others VMs, have less RAM (4GB) and are not so bussy, running fine. So i have two indentical configured Hosts (PGSQL01 and PGSQL02) BUG: BUG comes every 3-8 days.
