Par2.exe occasionally runs forever

[blun7]

Sometimes par2 will use 100% of my cpu until I kill par2.exe. I tried letting the repair run for a long time but the web interface reports the same percentage of completion for a very long time.

I'm running rc3 on Vista 32-bit . I've had other nzb's with the same problem but very few. Here is one newzbin report that caused the problem: http://www.newzbin.com/browse/post/5494812/

There has been quite some discussion about this subject.
Either par2-multicore is buggy (but marginally so) or it is very
good at exposing marginal hardware (especially memory).
In 0.5.0RC6 there will be an option to revert to the old and tried
(but slower) par2 classic program.
RC6 will be released soon.

I'll check your example anyway.

This is assuming that you use 0.5.0RC3 and not 0.4.12.

Checked your example.
Downloaded and repaired without problems.
So it's not the downloaded material a such that causes the problem.
Still, could be a bug, bad memory or anything else really.

What happens of you run par2.exe repeatedly over the downloaded files?

Code: Select all

cd /d c:\where\your\files\are
"c:\program files\SABnzbd\win\par2\par2.exe" r FIRST-PAR2-FILE

Thanks for the response. I had repaired the files with quickpar so I'm unable to attempt. I will try next time it happens, if it does. I've installed rc6.

Should it happen frequently, you can use the par2_muliticore=0 setting.
