The server is a rather bare bone server for web mapping, so basically PostgreSQL/PostGIS, Apache, PHP, Tomcat and
littleother stuff. The Dell software was the only which did not come from CentOS/EPEL/argeo/in-house RPM packages. I've
removedthe Dell stuff completely, but the problem is still there.

Other informations: disks are costly SAS drives in a RAID 1 array, memory is with ECC.
Security level is disabled
SELinux is Permissive.
The server acts as a XEN host 

Is it reasonable to restrict the problem to kernel/hardware and/or PostgreSQL/PostGIS itself?

Can I trace where the SIGTERM comes from?
