0.7.11 Intermittently Quits [OS X]

[shypike]

Thanks for your detective work.
We're still at a loss as to why this happens.
Especially because most people (including the developers) don't have the problem.
I'll check the build history again.

I've also been seeing this, usually every day but it can skip a day or two and have some additional hints as to cause. It looks like this is the same as the the issue reported here: https://forums.sabnzbd.org/viewtopic.php?f=3&t=8972

When I was looking at it this morning I noticed something in the system log that correlates to the failure:

Code: Select all

11/23/13 5:45:19.000 AM kernel[0]: PSYNCH: pid[28678]: cvwait: thread entry with same sequence already present
11/23/13 5:45:19.000 AM kernel[0]: PSYNCH: pid[28678]: cvwait: thread entry with same sequence already present

In some of the crashes I've noticed a thread with a stack like:

My Config:
python 2.7.5 from macports
py27-cheetah @2.4.4_1
OSX 10.8.5
SABnzbd 0.7.16 from the Python source tar ball. I have not been using the OSX package.

Interestingly, I've just noticed that I do not appear to have a version of yenc installed in my python 2.7 environment but SAB has been working for me other than this occasional problem. Is yenc still required?

[shypike]

The yEnc module is only needed for speed.
With a fast CPU you won't see much difference.

The only thing that this tells me is that yEnc isn't the source of the problem.
Beats me what it is.
I have two Macs (one Mountain Lion and one Mavericks) and neither one has the issue.

[alcuin]

Add me to the list of OS X users with the same problem.
sabnzbd just crashes almost every night.
Here's the top of the latest crash log:

It's the ready-made OS X package I use and it's running on OS X 10.8.5.
Python is V2.7.2 (guess it's the one that came with OS X or the Xcode tools, never upgraded Python manually).
If I can help in any way just drop me a line.
