What's the full version of MarkLogic? If you don't have the latest support 
release, try upgrading.

Assuming that doesn't help... what's the server doing while the browser is 
spinning?

You said you've already checked ErrorLog.txt? Have you tried setting 
file-log-level to debug or higher? Naturally you'll have to re-run the request. 
You may not see any log messages for your application, though. That depends on 
what the original app developer decided to log. Then again you might see 
something like multiple threads in XDMP-DEADLOCK, or something else.

Next I'd visit the port 8001 host-status page. That will show you all app 
servers, with the active queries. Click through to the app-server status page 
for details.

If there are no long-running queries that seem to match up with the browser 
requests, then it's a browser problem: debug it with the browser console and 
other tools.

If you identify long-running queries that seem to match up with the browser 
requests, you can use the '[stack]' link to try to debug them. This doesn't 
always work, because the thread has to respond to the debug flag. But it's 
worth trying.
