OSX Monterey - Sabnzbd stops listening: OSError: [Errno 57] Socket is not connected

[jc123]

Strange stuff. I would lose the web interface from time to time (not sure what is triggering it.

I was having issues with the latest release so I'm now running the develop branch on the command line and I'm getting the following error:

Any suggestions on how to troubleshoot.? I'm on the latest OS release and python3 version 3.9.13

I'm only using HTTP and this is happing on the localhost.

I would put the trace in but the submit thinks that there is a link in there and denying me.

The last function was parse_request().

Again, it's random and on localhost

Put the log / traceback on a pastebin and post the link (add some spaces so that the anti-spam feature doesn't kick in).

Interesting clue - I changed the config to use 127.0.0.1 and didn't crash the web interface but using 192.168.4.16 (my internal address it crashes the listener with the first error being at: return self._sock.recv_into(b)

What's interesting is that Mylar is also dropping the listener from time to time. I'm changing that to use 127.0.0.1 and see if it fixes it.

Thx for any suggestions.

Update - I had the SABNzbd Host value == my IP address and at some point the listener would stop. I changed to 0.0.0.0 and it worked for awhile but then still stopped listening,

However setting the Host to 127.0.0.1 lets the app run for days without a crash.

Very strange - version: develop
os: OSX Monterey

debug: (replace spaces with slashes except between bin and .com )

Do you run SABnzbd from source (and not from the DMG image)?

Reason: it looks like you're using your own python instead of the python provided in the SABnzbd DMG package. Oh, it also looks you're using your own cherrypy, not the one provided by the SABnzbd DMG. Disclaimer: I'm not a Mac user, and I had only a look at the contents of the DMG pacakge from Linux.

OSError: [Errno 57] Socket is not connected

Googling "OSError: [Errno 57] Socket is not connected" leads to IOS and MacOS hits (and a bit lesser FreeBSD), and "race condition". But ... very old bugs, not something recent, so not helpful for this case.

Thanks for the quick reply. I'll go see what the differences are between what's in the app and what I have (since I built the deployment from the github develop branch.

Ah, as I guessed.

Please try the DMG image.
And if you want bleeding edge, github also provides DMG development versions. But that is for later.

EDIT:
1. You're using MacOS, so I assume you have no firewall and no virusscanner?
2. what can access your SABnzbd? Devices from your LAN? Or also Internet? Are you using any nasty network clients / scanners / etc? Cherrypy (in which the error occurs) can bail out with nasty traffic scanners
3. are you using HTTPS on SAB's webinterface? If so, can you turn that off temporarily?
