We have an application running on WebSphere. Requests are often running for a long time (tens of minutes). Our users report that Internet Explorer breaks connection and shows blank screen after some time of waiting. The application log says that requests are finished normally at the servlet level, though it gives a number of errors like this:
[4/24/15 11:31:19:253 MSK] 0000001f ThreadMonitor W WSVR0605W: Thread "WebContainer : 2" (00000027) has been active for 750529 milliseconds and may be hung. There is/are 1 thread(s) in total in the server that may be hung
What are configuration options of WebSphere or Internet Explorer, that should be considered while resolving the problem?
