sabnzbd not closing connections to server down properly?

Post by trmentry »

I'm not totally for sure if this is a sabnzbd issue, but thought I would ask just in case.

Version: 0.4.9
OS: Ubuntu Hardy (8.04)
Install-type: Linux Manual
Skin (if applicable): Plush
Firewall Software: pfSense
Are you using IPV6? nope
Is the issue reproducible? kinda

Stunnel4 = 4.21

I have my linux server also running Stunnel4.  I have sabnzbd setup to connect to localhost:119 for the server.  Stunnel will grab it and then relay on to giganews using their ssl connections.

What I notice from time to time is that my speed will degrade on downloads.  If I restart stunnel, things clear up and are fine.

When I restart stunnel I will see an awful large amount of CLOSE_WAIT on a netstat.  For example

Code: Select all

~$ netstat -a | grep nntp

When I restarted stunnel, I got my 10 to localhost and 10 to giganews like I expect and then speed was back up to max.

I'm not saying sabnzbd has an issue, just wanting to check if anyone else has seen an issue like this.  It very well maybe a stunnel thing.

Thanks

Hrmm... ok.... I did a bit more Googling and found the following:

https://bugs.launchpad.net/ubuntu/+sour ... bug/327222

I'll see if I can take my Stunnel from 4.21 to version in the post.

Sorry for the cruft.

Do you need to use stunnel?
SABnzbd supports SSL connections.

I'm currently running 0.4.9 and it shows it as disabled option in the server setup.  Tick box is grey'ed out.

Hrmm.. looking in changelog, looks like it's been there awhile.  But it's always been grey'ed out for me in my web interface.  thus my stunnel work around.

I'll dig into that and see if I borked something in my ini.

Install python-openssl (pyopenssl).
