It doesn't look like a power problem. We have it with several systems  
in different datacenters. I've tried the "giantlock" setting, let's  
hope it works! Am I safe to assume that it can (negatively) impact  
performance of the system? What can be the cause of "fine grained  
locking" causing the crashes? I'm willing to let a developer play  
around with one of the affected machines...

Thanks again for the suggestion Ulrich.

Met vriendelijke groet / Kind Regards,
Rutger Bevaart
