100% CPU load when downloading anything

[WeirDave]

Recently I have been plagued by a 100% CPU load when I try to download. If I pause the download normal CPU cycles continue. This happens on any download. If I have a single file or multiple files. After googling the issue I saw a post from a couple of years back that sad to attempt to do a que repair. This did not fix my issue. Any other suggestions?

v0.7.20

Thanks in advance,

What kind of hardware and OS?

Hi guys, new to the forum. I just installed sickbeard, couchpotato and sabnzbd in Ubuntu and am having the same/similar issue. Sabnzbd starts and everything runs smooth for a little while. Downloads start and shortly after the GUI becomes unresponsive.

Setup:
Ubuntu:14.04 (VM)
RAM: 6GB
CPU: 1 socket with 6 cores
Sabnzbd:

As I was typing the reply I noticed several entries of the following error in Sabnzbd:
********************************************************************************************************************************************************************************************************

********************************************************************************************************************************************************************************************************
I installed the whole setup using this guide:

Thank you in advance for your help!

WeirDave, were you able to resolve this? I am having same/similar issue

Kozunak,

If you set Logging to +Debug (via Status -> Latest Warnings -> Logging) and restart SABnzbd , the sabnzbd.log (via Status -> Latest Warnings -> Show Logging) will show a line like "CPU Pystone available performance is 83028". What does your logging show?

Furthermore, on Linux (and other Unix-like?) systems, SABnzbd shows in the upper right corner something like "Sysload: 0.00 | 0.01 | 0.05 | V=334M R=24M". What do you see there?

Here is the info requested:

2015-03-02 08:09:03,046::DEBUG::[sabnzbdplus:1294] CPU Pystone available performance is 268456

Sysload: 0.00 | 0.01 | 0.05 | V=3538M R=44M

Wow ... that is a beast of a machine, and so the CPU load is low "0.00".

Where do you get the information that the CPU load is 100%?

[kozunak]

Yeah, I threw more resources at it to try to remedy the situation Ideally, I would like to scale back. To answer your question, I get that info from PRTG monitoring that host. The CPUs show to go to 100%. I am assuming the Sabnzbd gui would also show 100% but it is unresponsive so I am unable to get the info that way...

[sander]

scale back to what?

[kozunak]

Scale back the resources provisioned to that VM...right now it has 6GB of RAM and 6 cores for CPU.

Please be exact: what are the resources provisioned to that VM?

CPU:
- 1 virtual socket
- 6 cores per virtual socket

RAM: 6GB

HDD:
- OS and applications Installed and running on SSD
- Media stores (TV, Movies, etc) are stored on NFS
- NFS shares are on FreeNAS 9.3 that is presenting the storage as ISCSI to ESXi. The disks are spindle type running in RAID5

[sander]

Well, with high spec hardware you describe (pystone above 200000, RAM 6GB) I can't imagine you get 100% CPU due to SABnzbd downloading.

[kozunak]

I would agree with you but I can replicate the issue 100 times a day Here is a screen shot of PRTG polling the CPU usage. You can see each core spiking to 100%

Also, I am getting the following:
Error when trying to navigate to the GUI while Sabnzbd is downloading and CPU at 100%

Did you search

File "/usr/share/sabnzbdplus/cherrypy/_cprequest.py", line 579, in run raise cherrypy.TimeoutError() TimeoutError

on this forum? Including the possible causes, like a HUGE queue.
