Message 1789801 - Posted: 23 May 2016, 16:24:52 UTC

Hi,

I have a SETI@home v8 8.00 task that has been stalled at 99.730% complete for a couple of weeks now. Other SETI@home tasks have downloaded, completed, and uploaded, and this one task just sits there. I have tried suspending it and then resuming with no response.

Any ideas about how I can get this task to complete?

Thanks,

David

It should be this task:
http://setiathome.berkeley.edu/result.php?resultid=4920821023

Try a few more "suspending it and then resuming" - the app is probably stuck in "Optimal function choices"


More Advanced:
- Find your BOINC Data directory (in the start of Event Log (Ctrl+Shift+E))
- go to slots\ directory
- in one of them find stderr.txt - open it and post contents

- look in state.sah - near beginning you may see <prog>0.99730000</prog>

Hi BilBg,

Thanks for the response. I tried suspend/resume about 50 times with no change.

Hi BilBg,

By the way, the task number you list is the one at issue.

Thanks,

David

I also found a file called sterrgfx.txt

It appears to show a lot of failed to load messages. I'd hate to abort with it being so close to the end. Should I abort the task?

Thanks again,

David

Message 1790160 - Posted: 25 May 2016, 3:03:57 UTC - in response to Message 1789838.  

Failed to load 'user_logo'.
Failed to load 'background'.

Nothing to worry about these, they are normal Messages (they are "by default") because user_logo and background are custom files which normally don't exist.
Only if the user wants he may supply in SETI@home preferences "URL of background image" and "URL of logo image"


I tried suspend/resume about 50 times with no change.

How long do you wait (e.g. 2-3 minutes should be enough) after resume?

I'm almost sure the app is hanging in "Optimal function choices" (which don't depend on task), this is long (years) existing bug in stock CPU apps.
If the app passes the "Optimal function choices" (startup phase) it will continue with the task and not hang during its processing.

You can see the app is doing real progress by:
- in Windows Task Manager, on Performance tab - from View menu check "Show Kernel Times" - then "too much" Red will mean the app is hang in "Optimal function choices"
- date/time of state.sah will change every minute (that is the checkpoint file)
- the <prog>0.99646484</prog> inside state.sah will change (increase)


Did you try to reboot?

P.S.
I know how to avoid this hang (and compute much faster) but you will lose the SETI@home screensaver

To try this "fix"/improvement - use the Lunatics installer (to install optimized applications):
http://setiathome.berkeley.edu/forum_thread.php?id=71867&postid=1758149#1758149

Again: optimized applications don't have screensaver

Hi BilBg,

I have waited more than 2-3 minutes multiple times with no luck. I looked at the Kernel times info and it is 80-90% red.

I have BOINC on my laptop so it gets rebooted everyday.

This is the first time this has happened so I think I am just going to abort the task and hope it does not happen again. I like the screen savers so I want to keep them. If it does happen again I will follow your instructions on disabling the screen savers.

Thanks for your help.

Regards,

David
