Wepshere and ColdFusion Mx 7- Java Hangs
Hi folks,
We just recently went live with our new web server and are experiencing
occaisional hangs with Websphere/CF. IBM has diagnosed the following, and I am
hoping you might be able to help shed further light on how we might correct or
alleviate the problem.
I see out of memory exceptions and the current thread is deep in ColdFusion
code...

And
The heapdump also shows coldfusion code with large 8M objects. This is the
source of the problem.
