Constant Cancelled Queries in F12 Console

CodyPatterson

Hey all,

I've received continuous reports that our Enterprise environment is the slowest thing anyone has ever used in their lives. These are quite discouraging comments as the Enterprise environment is quite a heavy task to create and setup.

I decided to connect to our environment at home and connect to a frequently used map, and after around 30 minutes of loading, I went to the console to try and figure out what was going on. I found these here, hundreds of these:

All are slightly different, but the requests are failing, only partial features load, and typically it takes around 15 minutes between click and data load.

We are using an Apache 2.4 reverse proxy, which I believe may be the bottleneck. We have 16GB of RAM and 4+ cores assigned to ArcGIS Server and Portal, what else could be happening here?

Thanks in advance!

Hey all,

An update, I've found what was happening, we have two ArcGIS Servers, one a workflow manager server and the other our main ArcGIS Server. I was performing some packet analysis and checking out the flow through our reverse proxy, and found that there was a query going back and fourth between the servers, consistently building data, around 50MB a minute. When everything failed, it hit 50GB, which is quite concerning, I've placed some outgoing filters and inbound filters, and that has ceased any queries doing this in the future.

A restart of both servers is a temporary fix.
