Looks like "hot" has been stuck for a while again... won't be home to kick it for a while.
Don't worry... Lemmy hasn't suddenly gone quiet, you can view by new still :)

Restarted just before this comment.
Ok, this is now scheduled to occur hourly, on the hour. Will cause a few seconds of 502s while lemmy is restarted.
what is the instance running on at the moment? perhaps it might be helpful to have some load balancing fronting the instance
Details on the server stuff is over here.
This issue isn't load related, simply a bug. Load balancing wouldn't help in this case.
thank you for the information
let us know the error/warning message, let's see if anyone happen to have the knowledge. Remember to redact some key info
If you get the error, it will literally be "502 error" on a plain white page. Chances are unless you've just clicked a link or hit reply/submit, you'll never see it.
The likely reason would be server overload, haven't look into the lemmy stack. Perhaps monitor cpu, ram and cache usage (if any) to see if there is any correlations to the 502s
No... 502 is due to me restarting the lemmy process, due to the known bug I linked.
understood, i guess it is up to the dev or pull request to fix it for now
And again just now.
And again
again
I've disabled the restart, as it risks losing federated messages.
I did see mention on that Git that restarting the server will break federation, in that outbound changes are held in ram
Hmm good call out. I hadn't thought about it, but would have assumed there was a DB table with pending outbound sync tasks. Kind of make sense for this to not be the case.
I think I'll disable the restart cronjob when I can. Better to have a frozen "Hot" timeline than federation issues.
Damned if you do, damned if you don't - I don't know enough about Lemmy if the ram federation thing is true but no one on Git has disagreed with it yet
(Actually checking this issue #2142 it seems as if it is the outgoing federation activity sync fails that remain in ram for retry)
Yeah I've stopped the restart cronjob.
Would it be worth chucking in an hourly restart cron job/systemd timer for the time being? Not an ideal solution for sure, but maybe that's better than having to jump into the server every few hours (and users experiencing a seemingly stale feed).
Yeah, on my todo list this weekend. Devs have stated there will be no further 0.17.x releases, though the fix is in 0.18... with no ETA currently.
