Sentry unable to run on PCF

I tried to deploy sentry on PCF, but I got the following errors that don’t look like errors. Any idea what does these means?

However you set this up, it looks like Django → stderr → something. And the something assumes everything on stderr to be an ERR. Stupid something. :wink:

Same thing on journalctl:

Feb 17 14:46:19 vm-jessie bash[4300]: WSGI app 0 (mountpoint=’’) ready in 4 seconds …

In a nutshell, your server is very likely up and running.

Yeah, all of that output is normal. Everything is working fine.
