Environment : Intel Q6600 quadcore, Ubuntu 9.x (errors happening on both 9.04 and 9.10), BOINC automagically installed from .deb package, or running as shell-script.

The problem : BOINC throws computation errors every now and then. Happens when i'm unable to connect to the internet, and Linux is trying to find a router, or when i'm copying files, so the disk is unavailable for a while. I just see the processor use drop down, one task at a time.
'Messages' says nothing special, just 'computation finished'. Problem mainly happens when running LeidenClassical, but has appeared on WCG as well.
Anyone who can shine a light on this?

Could be a problem because BOINC is not able to checkpoint. However, I am not sure exactly how the client works.
