Re: Strange crash logs

[Rocco Zanni <rocco.zanni@xxxxxxxxxxxx>]

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
