BoincLogX appears to ignore DCF.
True, once a WU is running the estimate is simply based on progress and CPU time. That works very well for AP WUs, but at the very beginning of setiathome_enhanced WUs provides some amusingly huge estimates.
BoincLogX does use DCF for estimates of unstarted work, though.

You seem to have had more than one of those errors on the same computer:
http://setiweb.ssl.berkeley.edu/beta/result.php?resultid=4086296
http://setiweb.ssl.berkeley.edu/beta/result.php?resultid=3930831
Do you have anything like a virus scan that accesses the BOINC folder regularly?
No problems with 4.33 until now. Estimated runtime: about 43 hours per wu.

I run a virus scan. I'm not sure how to figure outif it looks at the BOINC folder. Even so, why would I get this error? My other BOINC apps don't seem to mind.
Thanks,

Got the firt error using 4.33.
1148968 went through as a redundant result. I don't know when exactly this happened. We had a line of storms go through last night and we lost power.

This was an Enhanced v6.02 result - not AP v4.33.

I got a WU which ran in the checkpoint errror. After restart the WU exited immediatly. So I restored from the backup, and the WU continues.

That at least means the checkpoint works sometimes. I'm wondering if there might be a race condition in it. Thinking that if the O/S is going down it may send signals to both the Boinc Manager and the AP process at the same time. AP may then get another from the Manager as it cleans up and not save correctly.

Ugh. First the eyes go and then the brain.... Sorry.

Some virus scanners may lock files while they are scanning them.
The AP application probably needs exclusive access to its files.
Which scanner do you use?
In most virus scanners it is possible to exclude certain folders or files from scanning.
I just had my last 2 AP tasks error out on a -4
In ap_fileio.cpp, Statefile::write, statefile is 0'd, trying again: iteration 100
Error calculating fold_level.

About this time I had to log off as I couldn't open Boinc Manager and the computer was real sluggish. Processors were at 100% but then they always are. However on checking the logs it appears to have crashed during logoff "The previous system shutdown at 8:25:42 PM on 30/06/2008 was unexpected." Nothing else obvious shows up.
That should have said 3

I run a relatively old version of Symantec Antivirus. I'll see if I can exclude files.
I'm not sure I am comfortable with this explanation. Windows apps should be able to retry or somehow get around trying to read a file that is being virus scanned. Admitting that I know nothing about AP, why should it be any different than other Windows BOINC apps that don't have this problem?
Thanks,
Jim

These errors look a lot like what I was getting as well. I am also still getting "Can't delete previous state file" and I am running Vista with OneCare.
I am not convinced that the issue is not with BOINC not properly closing files but I can never catch the file in a locked state.

Hi guys, have have successfully completed several wu's & have 2 currently crunching. However, one of them seems to be acting up. On several reboots since the weekend, it has restarted from 0, yet the completion time still states 02:03. It's currently showing 13:03 completed. This hasn't happened with the previous wu's, so should I let this continue or abort?
WU - 02/07/2008 02:39:31|SETI@home Beta Test|Restarting task 23ap08aa.14671.4980.3.11.23_1 using setiathome_enhanced version 602
Also, can someone tell me how to link it's url? - sorry, found it.

Various programs that allow multiple users to access the same "file" follow different rules about what happens when the file is open and someone touches it. Any Seti application follows the Common Sense Rules. Virus scanners tend to ignore those rules, IF they trap a virus they want to insure they have it LOCKED! Then it can not do any damage. That is a reason why people tell you to exclude BOINC and any Project Applications and/or directories.
I hope that makes more sense...

Pappa,
I think (sometimes it takes me awhile to figure out what I want to say) my point is that AP seems to be the ONLY BOINC app that may have this issue. Why would it be different from the others including SETI and SETI Beta?
Thanks,
Jim

The primary difference from other apps is that Josh has put the "Error reading from statefile: wanted 2832 bytes, got 0" message in place, _enhanced simply starts over from the beginning of a WU if its state file is empty. That issue has reappeared many times, though it is rare enough it's impossible to reproduce for testing. See the Resuming WUs doesn't work reliably thread from late 2005 for example.
I have hopes Josh will find a fix which can be ported to _enhanced also.
