Notifications stop working after upgrade to version 2.1.3

Summary

After the upgrade to HipChat 2.1.3, notifications stop working.

Steps to Reproduce

There are no clear steps to reproduce the issue. It seems related to the presence of file /etc/init.d/ovflan in the server before or after the upgrade.

Expected Results

Notifications working as usual after the upgrade.

Actual Results

It seems that Consul and Chef get stuck in a loop, causing Chef to run approximately every 6 minutes. This can be verified by running the following command:

grep "Creating consul session" /var/log/chef.log | awk -F+ '{ print $1 }'

If the service is being restarted, it's possible the bug is affecting the server.

Curler/Gearman also gets restarted, in turn:

grep "curler-export: \[\-\] Starting factory" /var/log/hipchat/gearman.log | awk -F. '{ print $1 }'

Output should be similar; restarts approximately every six minutes.

Notes

This seems related to the presence of file /etc/init.d/ovflan.

Workaround

Run the following commands from inside HipChat Server command line/CLI:

sudo dont-blame-hipchat
mv -v /etc/init.d/ovflan /root/ovflan.bak
cs
hipchat service --restart
