All the milkyway@home work units I get start and then finish immediately and give the same error:

Exiting..."

I have a fresh install of ubuntu 11.04 (x64) with the latest ATI drivers and boinc 6.10.59 installed from the ubuntu software centre. The system specs are; intel core 2 duo e4500, 2gb ram and radeon 3870.

This system had been running collatz conjecture (on the gpu) and rosetta@home/einstein@home on the cpu for a while under windows without any problems.

Win 7 64bit, 2x4870 11.3cats(?)

Started getting errors last Friday after running for a few months with no problems, it would freeze my rig as soon as mw started, if I only ran wcg on the cpu it was fine, I switched over to collatz Friday evening and no problems since.

I think I read they were trying something new for the time elasped bug, not sure if it has been implemented yet
