Hmmm, I would ask Synology (forums) for this. I don't have this specific router so can't help.
Maybe Google knows?

Maybe you can enable Debug logging in the Status window and then after it happens again, click Show Logging and inspect any network events. Maybe it's disconnecting or loosing connections?

On startup you can supply a repair parameter to the script, you could run that by default?

You can look at noofslots_total, if it is 0 than there's nothing in the queue.

You are missing python-dev package.

Alternatively you could also download the logs. First switch logging to Debug in the Status window and then after it happens again, click Show Logging.
(this assumes you use the Glitter interface)
Maybe there's something in there about stalling connections maybe?

I would then suggest to try the fresh start, it should keep your history just reset your settings.

Did you maybe set jobs to be added Paused in the Categories settings?
You can always try this: https://sabnzbd.org/wiki/faq#freshstart

Maybe a bit clearer: what kind of crash do you mean?
Does the browser close? In that case it's not SAB, it's just some browser problem.
Or you see a crash in the interface of SABnzbd?

That's a problem of your ipad, not the server.
From my own experience I know it helps to clean the browser cache, there's a setting burred somewhere deep to do that.

Usually the limit you to a number of Gb, usually still a large number like 20GB.

I know, didn't spend time yet to fix it:

Je moet via "Browse"/"Bladeren" proberen naar de map op je schijf te gaan vanuit SABnzbd.
Deze functie laat je ook direct zien welke mappen SAB wel/niet toegang tot heeft.

I just said that par2-tbb isn't available for pi3...
Please use par2-mt

par2-tbb isn't available for pi 3.
You should use par2-mt, but also make sure you added the apt-sources correctly.
