I have now encountered the following error in the Messages log on 3 different CEP WUs:

In this latest example the WU apears to run for about 4 minutes, generates this error message and then seemingly restarts.

On a previous occasion the WU appeared to be almost to the finish, generated the error message then appeared to restart at about 95% complete.

On this previous occasion I eventually reset whereupon BOINC downloaded all current and queued WUs, restarted the problem WU ran to the same point and the problem reoccurred. On this second occasion I aborted the WU.

I would like to know:

a) Is there problem with certain WUs or a set-up problem on my PC?

b) What is recommended action when this problem appears?
