Eccezione lavoro: JavaScript è stato terminato (per timeout o esplicitamente)

Supporto Installazione

Ho appena migrato un’installazione Discourse più vecchia (1.9.0.beta5) su un nuovo droplet di Digital Ocean con tutto all’ultima versione. Dato che la versione precedente era molto vecchia, non ero sicuro che tutto sarebbe stato trasferito correttamente, ma sembra che funzioni bene.

Tranne il fatto che si blocca ogni poche ore.

Questo è il registro degli errori che ho ricevuto alle 00:57 di oggi:

Il sito era non responsivo quando ho provato a caricarlo questa mattina; ho ricevuto un errore 504. Il server era ancora in esecuzione e il log in ./launcher log app mostrava ripetutamente quanto segue:

ok: run: redis: (pid 48) 11912s
ok: run: postgres: (pid 47) 11912s
supervisor pid: 26654 unicorn pid: 26658
config/unicorn_launcher: line 71: kill: (26658) - No such process
config/unicorn_launcher: line 15: kill: (26658) - No such process
(26654) exiting

Dopo un riavvio alle 9:00, il sito ha funzionato correttamente per alcune ore, poi si è bloccato di nuovo alle 11:04. I registri degli errori sono sostanzialmente gli stessi in entrambi i casi. Un altro riavvio ha risolto il problema (per ora). Continuerò a monitorarlo e riavvierò quando necessario finché non risolverò definitivamente la questione.

This is likely load related, how is CPU looking on your server? How is memory?

Site seems to be stable since those two crashes. CPU and memory use are normal. I don’t know what they were during the downtime. Perhaps there was some heavy load initially due to the transition.

I’ll update this thread if anything happens.

Just crashed. I rebooted the server again, and it is currently using 70-80% CPU. It is converting jpgs for some reason, and we have a lot of photos. I’ll reboot as need, hopefully this is a one-time task.

Crashed again today. Before restarting, I noted 97% of CPU is going to this process:

ruby /var/www/discourse/vendor/bundle/ruby/2.6.0/bin/unicorn -E production -c config/unicorn.conf.rb

Overall memory usage:

  3073648 K total memory
  904712 K used memory
 1510576 K active memory
  376240 K inactive memory
  815448 K free memory
  306872 K buffer memory
 1046616 K swap cache
       0 K total swap
       0 K used swap
       0 K free swap

Any insights on what this particular process does?

The way that images are stored changed a while back and they’re all being processed. There’s stuff that’s supposed to keep it from crashing x but it’s not enough for you. I would recommend increasing your ram for a while until they’re all done.

I think that there is a site setting that controls how many images are processed in a batch, but can’t quite remember what it is this instant.

Thanks. I suspected something like that. We have 15 GB of images.

I’ll keep an eye on it, and just reboot as needed.

More specifically, the srcset attribute is now supported on the <img> tag so retina devices see higher resolution images. This means more copies of images as a side effect, because you have multiple display densities to serve with the same image.

See https://html.com/attributes/img-srcset/
