Just as a sanity check - could you try removing that single parameter and see whehter that makes a difference?

Answer by Harald B. · Oct 01, 2014 at 07:01 PM

Amol,

Please consider that getting parameter (like using the * operator to get all parameter) can be very expensive. One quick sanity test would be to disable parameter capturing

regards

Harry

Are you planning on upgrading to dynaTrace 6? It seems you are still on 5.6 - so - an upgrade would be interesting and see if that has a positive affect.

I am not aware of a known issue in the IBM JVM - but - in the past we on and off had customers with some issues with the IBM JVM. We keep improving our implementation for IBM JVM - thats why I am wondering if you could upgrade to benefit from the latest improvements.

You could also open a support ticket and referencing to this forum post. Maybe my colleagues from technical support know about this behavior

Hi Amol

Thats interesting. Can you attach a screenshot of your Servlet SEnsor Properties Dialog? The stack trace you attached shows that this is the dynaTrace code that captures Servlet Parameters that you want to capture. A quick look into your configuration would help to better understand what the problem might be

Also - can you provide the exact version and platform information of your IBM WAS?

Thanks
