Hey Guys,

I have been using sabnzbd on my mac mini for about a year now, using it with giganews' platinum account has been great and up until recently everything had been working fine.

Any nzb I add to the queue that is over a certain size (somewhere around 2GB I think) will fail with a CRC error when trying to unpack. I have tried about 50 different nzbs of various large sizes and they fail every time.

Starting to get a bit frustrated, I am hoping that it is not down to a hardware fault of any kind and that it is a problem I can solve without taking my mac apart.

Could it be down to corrupt memory / disk sectors? Or could it be my wireless card?

Our broadband service has changed recently to a different provider (including a new router) could this have affected it in any way?

Any help will be very much appreciated !!

Version: Currently 0.5.0beta, but problem occurred also with 0.4.12
OS: OSX Leopard
Install-type: OSx .app
Firewall Software: don't think so
Are you using IPV6? Not sure what this is
Is the issue reproducible? yes

it could be down to bad memory. I suggest you run a tool that exercises your memory and see if that's the problem.

I had this happen to me and it was my memory at fault.

Thanks a lot for your reply.

I just ran memtest on my mac mini, here are the results:

*** Address Test Failed *** One or more DIMM address lines are non-functional.

This doesn't look very promising....
I will try putting new RAM in the mini, and will see if that helps.
