SABnzbd causing full system crash on OS X 10.6.8

[perspeculum]

Hi guys

Been trying to track down the nature of this problem for some time but no joy.

I'm running SAB 0.6.15 on OS X 10.6.8 (installed via the .app). I have Symantec Endpoint installed for AV and the standard OS X firewall enabled although LittleSnitch is also installed. I am not using IPv6 to my knowledge.

Although the issue does not seem to be reliably reproducible, it seems to occur (but not always) when a major java event (eg an applet) loads in Chrome. Then if the crash occurs, it starts with Chrome becoming completely unresponsive. SAB appears to be carrying on but I usually pause it at this stage. If I have anything else up like music playing or a video running, this carries on as normal although aside from that, the whole front end of OS X seems to completely fail - I cannot switch windows, force close apps or even shut down the computer without holding down the power button.

Todays example of this was it crashing at the exact point I tried to load the live chat feature on this site (which for some reason has banned me, no matter what nickname I choose - is my IP blocked?).

Any help would be appreciated.

What makes you think SABnzbd is the cause of the problem?

I don't use it very often - usually in spurts for a couple of days at a time. It never happens for weeks, then within an hour of enabling it, it happens and has happened several times in the 24 hours since (the same has happened at other times when I've loaded it, this isn't isolated). If I don't browse the web, it doesn't happen either, so I'm guessing it's some kind of interaction between Chrome (or maybe Java) and SAB.

SABnzbd does utilize the connection quite a bit (obviously) and also the disk.
For the latter it's important that you set an article cache in Config->General (try 128M).
Do Safari and Firefox show the same behaviour?
Lastly, we don't recommend using a WiFi connection for downloading.

I've set the article cache and I'll see if that helps, thanks.
I do sometimes have Safari or Firefox running as well but if I can replicate the problem I'll try running one of them alone. Either way if the problem persists I'll post an update.
Regarding the connection usage though, like I said it's not that just Chrome slows down, after a few seconds I can't even shut down SABnzbd, or force close anything else.
