Hi Tom,
we've discovered more informations in the meanwhile.
It seems that a bug in our backup tools caused a freeze in the
database filesystem. The tool was stucked inside an xfs_freeze for a
several minutes and caused the kernel to terminate processes locked
waiting for write lock. One of this processes was postgresql.
I don't believe that was an issue on postgres-side.
Bye,
Rocco
