I'm running an Ubuntu 8.04 server with SABnzbd 0.4.6 on it. It runs great on it but I have one problem. It uses 44% of my 2 GB of memory.
It doesn't matter when SABnzbd is downloading or not(when i pauze the download), it just keep using 44% of my memory. Their is no download witch is being extracted. When I restart SABnzbd the memory usage become normal, but after a few day's runnning it becomes high again.
Some extra information:
The information I get with the command: top
5379 root 20 0 1094m 828m 3684 S 10 44.0 357:42.38 python
The boot script of SABnzbd:
Code: Select all
#! /bin/sh
case "$1" in
start)
echo "Starting SABnzbd."
/usr/bin/sudo -u root -H python /usr/src/SABnzbd-0.4.6/SABnzbd.py -f /root/.sabnzbd/SABnzbd.ini
;;
stop)
echo "Shutting down SABnzbd."
/usr/bin/wget -q --delete-after "http://192.168.1.250:8082/sabnzbd/api?mode=shutdown"
;;
*)
echo "Usage: $0 {start|stop}"
exit 1
esac
exit 0

What did you set as a article cache (Config->General).
Limit it to 100M (do not set it to -1).
It doesn't do this on my own Ubuntu-server 8.04 box (with 700M).

I just changed what you said
the memory keeps the same, and in the webinterfece i get this extra message:
72 articles buffered in 27648000 bytes

The message is OK, it means that you now have an article cache (means less disk access).
So it looks like you didn't have one first.
Which doesn't bring a solution.
So either there's a memory leak in the SABnzbd code itself (nobody complained so far)
or you have a dodgy Python installation or dodgy modules installed.
You got them all by apt-get?
Do you have a huge queue and/or a high refresh rate for the queue?
Does the memory usage also grow despite an empty queue?
Do you have some other program doing http-api queries all of the time?
Do you have a Web browser accessing the queue page all of the time with a high refresh rate?
I'll do some checks on my own system.
There one difference of course: my programs don't run for days (being a developer).

No i didn't had one first, but its a good fucntion to reduce disk access. Thanks for that.
I just restarted the server (adding a new harddrive), and SABnzbd uses just 1% of my memory! But this isnt the first time that SABnzbd uses over 40% memory after a little while.
I'll check every hour the memory usage of SABnzbd without a queue this evening and i will post it when i see a change of usage. If that works good tomorrow i will add downloads and then check it every hour.
I got Python by apt-get, so i think that isn't a problem?
I don't know what a big queue is, i think I donwload quite alot. In the 2 days and 1 hour the system was online I've added 7 NZB's. The biggest NZB was for a download of 120 GB and the seccond biggest one was for a download of 15 GB. The others where around 3/4/5 GB.
On my system their are no http-api queries or other kinda things being excecuted
I have a few clients who look rarely on the Web interface of SABnzbd, so that is not the problem. The refresh rate is disabelt
For now I will just monitor the behaivor of SABnzbd and post updates if i got one.
Thanks for the help

OK, you download quite large stuff, which should not be a problem.
I just don't download so much myself.
I don't rule out the possibility of a memory leak, they are only very hard to diagnose.

Ok, SABnzbd has been running the whole night, with a normal usage of memory!
Now i just added 2 downloads witch both are 6 GB. And the memory is still normal. After this download i will add a bigger download an check if that is the problem.

Ok no problems so far! Memory keeps normal! I had to reboot my server and did some maintance on it. I changed the boot-up script of SABnzbd so when it start is runs on the background. Maybe that was the problem?
Well in the comming days i will see if it has helped. I just added 160 GB to my queue
thanks for the help!
