Since the Sha-1 Project doesn't even have their own message board to report problems I'll post this here and maybe it'll get to them.

The problem with the Wu's it that if you download say 50 of the Wu' 4 will start and run for a few seconds, then 4 more will start and run a few seconds, and so on until all 50 have been started and are in a waiting to run state with just a few seconds of run time on them. Then the BOINC Manager just jumps all around the Wu's, it will run a set of 4 for a little while then stop those 4 and start 4 more and so on until all the Wu's with the same Date & Time are finished.

Right now I have 198 SHA-1 Wu's in some form of running state or ones that have been started then stopped and are in a waiting to run state, this is on 8 Quad Core computers. What this is causing is either BOINC eventually crashs & or BOINC Crashs & the PC re-boots itself. This is with BOINC v5.10.13, I also tried the new v5.10.18 with the same results. I'm running Win XP Pro SP1 & SP2 across my Network.

It's the scheduler in the client. It doesn't seem to handle multiple results that are all under deadline pressure gracefully.

I forgot where I saw it reported before. It may have been posted to the alpha list...

Probably your right, anyway things seem to have settled down with the SHA-1 Wu's, I only have 32 running now on 8 Quads and none waiting to run. It's goofy, it'll run like that for awhile then take off and want to start them all up.

I lowered my preferences to connect so less will be downloaded and maybe downloaded at a little different times so hopefully they won't try to all start.

The same thing was reported by someone on apsathome today so that's probably where you saw it.

I'd be happier if the Boinc client tried to finish tasks from the same project one by one rather than trying to do them all simultaneously (it'd also reduce the boinc memory footprint) :-)

The following /Trac item mentioned it:

http://boinc.berkeley.edu/trac/ticket/305

Although I have to confess it was a fairly rambling ticket which covered several unrelated things...
