PAR2 fetching problem

I'm relatively new to SABnzbd and seem to only be having a problem if a NZB fails to download all blocks and requires more than just the one smallest parity volume to repair it.

Basically from reading about how SABNzb works on the board is that it download the smallest parity file in order to do a quick check on the archive to see if it requires repairing and will then go fetch as many other volumes as it needs to repair the archive. From looking at the logs I can see the parity check fail but don't see where or if it tries to fetch any other volumes.

I can provide a sample log of the activity, didn't want to post it in a case in broke some forum rules concerning its content.

Anyways basically I have installed this on my Thecus 7700 NAS Box using v 0.6.10, I'm not to familiar with the install process as it was a module put together by another user, but I assume it uses the linux/python2 scripting to have everything work properly and the user just built a wrapper around this code to have install as a module on the NAS box. I have downloaded the source code from SABNzb and done a few file checks and it seems to be all there.

I'm wondering its possibly something stupid as having spaces in the directory name which is causing issues as its on linux?

Also as a work around is it possible to have SABnzb not filter out the pars and just download all of them, as I don't really care too much about the additional downloads?

Thanks

Email more details (NZB, logs, settings) to bugs at sabnzbd.org
With the info so far, there's nothing to conclude.

I have looked at your info.
The only thing I can conclude is that the par2 program that you installed may have some issues.
Apart from QuickCheck, SABnzbd doesn't do any actual verification.
If QuickCheck fails to verify then par2 is always run.
For some reason par2 seems to fail randomly.

Thanks for looking at it, I will check to see If I can upgrade the PAR2, as I mentioned this was a module installed with the NAS box so perhaps it's not good. I do notice a warning concerning the UNRAR version not being recommended by sabnzb but I have no problems really extracting, it was just seeming to fail on the parity check

What was? Did unrar report CRC errors?
