SABnzbd+ consistently FREEZES my OS X 10.6.8 system

Actually, I'm not sure if par2-sl is truly multi-core like the Windows version is.
All I know about it is that it uses the "Grand Central Dispatch" of OSX.
It seems to work properly on most Macs.
That it doesn't show a full load on the CPU might be caused by it hanging in the central thread.
Is par2-sl ever working correctly on your system?
Other than that, you may never see a full load unless you have a large repair job.
par2 isn't completely CPU-bound, it uses the disk intensely as well.

Thanks for the info Shypike -- with more rooting around I see that indeed the default config of Par2 is using the MacPar deluxe engine that's optimized for Snow Leopard. Maybe we could ask that the docs be updated to reflect this and reduce any confusion for future users? I'm sure you must get tired of answering the same questions again and again.

So I removed the flag from the Par2 widget (now blank) and I made sure that downloads paused while post-processing. All my data is going to a Raid6 array via eSata and I may simply be hitting the I/O too hard. I'm now seeing Par2 running around 300% in the activity monitor -- so, to your point -- it may not have anything to do with Par2 other than my system may run better when I pause Downloads while post-processing. I realize this may be a red herring, but we are getting somewhere! Thanks again for your help. Do you have any suggestions of things I might try in order to get the same performance without pausing downloads?

We generally advise not to put the "Incomplete" folder on an external disk,
although a RAID array on eSata isn't that external.
However, RAID is rather wasteful for storing files for just minutes.
The redundancy overhead is wasteful for short-lived discardable files.

GREAT POINT! Were it simply a striped array perhaps it would make sense but since it is RAID6, I'm needlessly increasing disk activity. You are bang on -- thanks for catching that!
I'll move my incomplete directory to a local drive and keep you guys posted.

I recently just got back on my mountain lion setup and noticed its been freezing and the last thing in the console log is sabnzbd.

10/28/12 8:19:08.513 PM usernoted[184]: Cannot find originating application to launch for event action. file://localhost/Applications/SABnzbd.app/Contents/Resources/SABnzbd.app/ is not the same app as the one that sent the original notification.
10/28/12 8:19:08.513 PM usernoted[184]: Error finding application org.sabnzbd.SABnzbd.

Its the last thing in my log before it locks up. Ived used sabnzbd for as long as i can remember and it was fine on ML. Seems like its something to do with the integration with ML notification.

Not very likely.
Just disable the Notification Center support in Config->Notifications and see whether that makes a difference.
