CRC errors

[omisys]

I've recently installed a new ubuntu server running the 12.04 LTS. I just installed Sabnzbd and I keep getting CRC errors. I have tested the same downloads on my PC and over there I can unrar them just fine, on my server it seems to be impossible. I was running the multicore par2 version before, but i removed it and reinstalled the original par2 again to see if it made any difference but it didnt. I don't really know what could cause this problem so I hope you guys can help me out, its quite annoying. I'm running the 0.7.11 version of Sab btw.

You should also check the version of unrar that you are running.
You should not be using any "free" unrar, but only the official one from RarLabs.
If it's not in your repo, then use this: http://www.rarlab.com/rar_add.htm

This is the unrar that works for me on Ubuntu:

Code: Select all

sander@hapee:~$ unrar | head -2

UNRAR 4.20 freeware      Copyright (c) 1993-2012 Alexander Roshal
sander@hapee:~$

On Ubuntu, if you install sabnzbdplus via the Ubuntu Software Center, this unrar also gets installed

It seems that im running the 4.00 version of unrar. Could someone explain how to install the newer version of unrar on ubuntu server? When I run sudo apt-get install unrar it says that there is nothing to be updated.

[sander]

4.00 is OK, AFAIK.

Do a basic test: download one of these files: http://binsearch.info/?q=bigrandomfile& ... 00&server=

I know that the downloads are complete and im having it with about 50% of the downloads. They keep on giving me crc errors so maybe getting 4.20 solves something but I dont know how to get it.

Did you check out the URL Shypike gave you?

[omisys]

Yea but cant I just add it to my repositories?

I don't think so. But I neither think there is a difference between unrar 4.0 and 4.2 that matters to SAB

[omisys]

Well I managed to get it up to 4.2 but still it randomly happens. Sometimes when I download the Same file again it doesnt give the crc error. Could this be a RAM problem?

[sander]

You can run memtest86 from the GRUB boot menu. Keep it running for a few hours.

[omisys]

I ran the memtest and it didnt return any kind of errors. Still having this issue ._. . Any idea's left?

[sander]

I would do a manual unrar (assuming it happens unrar), and post the output here
