Howdy!
Since moving a lot of our users to 22.05.06, we've installed the worker
everywhere. But the number of issues encountered is staggering.
The first one was
Can't call method "process" on an undefined value
where the id received from MQ was not found in the DB, and the process
is going straight to process_job and failing. Absolutely no idea how
that occurs, seems completely counterintuitive (the ID comes from the DB
after all), but here it is. Hacked the code to add a "sleep 1" to fix
most of that one.
Then came the fact that stored events were not checked if the connection
to MQ was successful at startup. Bug 30654 refers it. Hacked a little
"$init" in there to clear that up at startup.
Then came the
malformed UTF-8 character in JSON string, at character offset 296
(before "\x{e9}serv\x{e9} au ...")
at decode_json that crashes the whole process. And for some reason, it
never gets over it, gets the same problem at every restart, like the
event is never "eaten" from the queue. Hacked an eval then a try-catch
over it...
After coding a monitor to alert when a background_jobs has been "new"
over 5 minutes in the DB, I was inundated by messages. There's alway one
elasticsearch_update that escapes among the flurry, and they slowly add up.
At this point, the only viable solution is to run the workers but
disable RabbitMQ everywhere. Are we really the only ones experiencing that?
Regards,
PS Our servers are well-above-average Debian 11 machines with lot of
firepower (ram, cpu, i/o...).
