Upgrading celery

Closed this issue · 4 comments

A few minor versions after the one OAG uses, a memory leak concerning celery worker timeouts was discovered and fixed. It is probably necessary to upgrade to the latest minor version of celery to avoid this issue.

Ah damn it.

Yeah, celery mem usage is slowly but very surely increasing. Quadrupled it's initial usage by now.

What needs to happen is:

  1. upgrade minor celery version locally
  2. check everything still works with a manual test of an identifier
  3. push to live
  4. watch the graph again

It's not much and I should most probably do it today unless you'd like to @nimphal ?

OK done the upgrade, let's see how the usage holds up now. We might have to run a batch of DOI-s if nobody else is to actually trigger the problem.

Memory is fine although we got a new problem with the upgrade: #119 .
