Any project stops immediately with "Computation Error"

I have just found out that every time my BOINC agent tries to start a World Community task it stops immediately with the status "Computation Error". I have no idea why - and tasks from other grid projects work flawlessly.

Re: Any project stops immediately with "Computation Error"

Hello ezrgrid,
I would try a detach from WCG then a new attach, for a start. I assume you have already tried a reboot.

Thanks Lawrence,

I forgot to mention that I have tried both to reset the project and detach/attach. And reboot lots of time.

Re: Any project stops immediately with "Computation Error"

Check to see what the results status page shows as the error, ver 6.10.17 is known to frequent the "Too many exits" error (bug?), suggest upgrade to 6.10.58 or better

Re: Any project stops immediately with "Computation Error"

If it still falls over after updating to BOINC7.x run memtest for half a day to see if it comes up with any errors. Are you running the package manager version or did you download the tar.gz file? if the latter, I usually upgrade by downloading the latest tar.gz and copying the files over the top of the previous version after unzipping.
