remote: Exception: {'error': 'notify_push timed out'}

[Taihsiang Ho]

When git push, there is such error message returned from the command line:

remote: Traceback (most recent call last):
remote: File "hooks/post-receive", line 222, in <module>
remote: 'pack_count': pack_count})
remote: File "hooks/post-receive", line 151, in rpc_invoke
remote: raise Exception(res)
remote: Exception: {'error': 'notify_push timed out'}

The return code of local git command is 0 a.k.a. successful. My local ref tree is updated as well. That is to say, my git thinks the remote repository is updated and aligned with my local branch. However, I don't see Launchpad webpage shows my branch is up-to-date.

Steps to reproduce: push local git repositories to your repository on Launchpad.
Expected results: No such Exception message and we can see the branch on the Launchpad webpage shows my latest commits.
Actual results: We have such Exception message and the Launchpad webpage does not reflect the latest commits.

Additional information:
This bug report is converted from Question #707451 https://answers.launchpad.net/launchpad/+question/707451 and seems that the issue is happening to many people.

This seems to be fixed.

This was due to a RabbitMQ out-of-memory outage, which affected any operation that tried to schedule an asynchronous job. We've resized the relevant VMs, and things seem to be working better now.
