Hi Guys.  
I am wondering if someone can help with this issue. I have a provisioning call back job that when initiated from a client, calls in to my awx servers and which in turn launches a job against that system. During development I was using a smaller inventory that has maybe 10 systems. After pushing to our pilot group which has over 2000 systems, I started getting a gateway timeout errors.  
Is there any way to get this to work on my large inventory?

I am having a very similar issue. I have a four node cluster running 14.1 and the callback works on three of the nodes w/o issue. However, on the fourth node it times out. I found the following KB on the Red Hat site: [https://access.redhat.com/solutions/5281311](https://access.redhat.com/solutions/5281311) and I adjusted the timeout to 600 seconds (10 minutes) and it still times out. When I run it on the three nodes that are working, I get a response in ~5 seconds or so.

Looks like it may be the size of the inventory that is causing the issue. I am not aware of an inventory size limitation in AWX. Is there one?
