We have a weblogic application talking to another weblogic application on another server.
We use JMS for communication between them. We're seeing odd behaviour where createTopicConnection takes 450 seconds (pretty accurately, so 7.5 minuutes) to complete one time, but the next time it will complete quickly, the time after 450 seconds again. It's not entirely consistent about the alternation, but it does this pretty much every time.
The two appliciations each run on single servers, and communicate directly. No Apache, no load balancers etc.
Weblogic is version 9.2
Can anyone suggest a cause for this? Also, a consistent 450 second is suspicious - is anyone aware of a timeout set to this value by default in weblogic?
