When I run Riesel Base Short on all (31) cores I get computation errors (output file missing). Also other subprojects then run into computation errors.
I limited cores to 5, but that's a suboptimal solution.

I can see only "finish file present too long". All the writings to disk with 31 cores is too slow and BOINC is killing the app after the 10s limit. At the moment its the main problem on the project. Perhaps someone can take a look into the wrapper code and find a better solution to get rid of this error.

This problem sounds a bit similar to what they have been discussing over at SETI and Milkyway in the Number Crunching forums. SETI is down for it's usual weekly maintenance but I found the topic at Milkyway.

Richard Haselgrove posted this at Milkyway > Message 63799 in Message boards : Number crunching : What is the cause of these 'validate errors' <

"After intensive work with Keith Myers and others (mainly in the SETI message board thread Stderr Truncations), I think I've finally traced and recorded the full life-cycle of these little beasties.

The easiest starting point is the debris left behind."

There is also a fix out but I dont know if its related to this error.

http://boinc.berkeley.edu/gitweb/?p=boinc-v2.git;a=commit;h=f2d690029c6dab9d586a9ba1a2e0af03dc7f3c70

Update:

The new boinc client 7.6.6 has this fix included
