Look at this host: http://setiathome.berkeley.edu/results.php?hostid=4974846 When it showed as my wingmate with inconclusive I thought it's usual GPU issue (task time of 28 seconds...) but not, it's CPU app.. But quite a strange one. All tasks I watched are restarted from 100% and have repeating patterns in signals found. Malice replication of few computed units? Or some issue with host where old checkpoint not deleted from prev task?... Any opinions? <core_client_version>6.6.31</core_client_version> SETI apps news We're not gonna fight them.

Any opinions? Only that we can only assume from what we see that the stderr is stuck from some prior run. The elapsed and CPU times differ, as do counts from time to time, so something is being launched, but either eororing before initial state can be written, or fully processing and failing to update state. I'd guess either damaged permissions on the slot preventing deletion, and/or a prior state file in the slot. Perhaps the old 6.6.31 client shown there has particular bugs in clearing the slot, or in sanity checks before launch. "Living by the wisdom of computer science doesn't sound so bad after all.
