Is proc_open required for Nextcloud Talk?

I get this log error twice a day at the exact same time. Talk is working and Mattermost app is not installed.

cron Error: Call to undefined function OCA\Talk\proc_open()

A simple question, is proc_open required for Nextcloud Talk or the Mattermost app?

#3

proc_open is required for Nextcloud Talk.

#4

Only if matterbridge (I think that’s what @NC100 is referring to) is used and for integration tests, but not for the “normal” Talk functionality.

Okay, thanks! Isn’t it strange that I get this log error when Matterbridge is not installed?

#6

This should only run if matterbridge is enabled: https://github.com/nextcloud/spreed/blob/c21f3f40ef583bf17f3e312b4f063afc1fb24a41/lib/BackgroundJob/CheckMatterbridges.php#L61
Did you enable matterbridge at some point?

Edit: Ah, no it tries to stop the bridges, that’s why you see this. Hm.

So there was a similar report at Error in logs · Issue #5958 · nextcloud/spreed · GitHub
Besides being annoying, there’s no harm in the error. I would just ignore it. If you feel this needs addressed, you can open a issue at the spreed repo, but the result might be the same as in the issue mentioned above.

Solved it by removing row OCA\Talk\BackgroundJob\CheckMatterbridges from database table oc_jobs
