Subject in-memory npe under load
Date Thu, 19 Mar 2009 02:06:41 GMT
Just checking if I'm doing something wrong here.

Simple receive/reply process - which basically does an echo.

When having a high load, it seems to get an NPE. Same process / same
load when using hibernate / oracle seemed to have handled the load
(while executing about slow by a factor of between 7 and 15 depending on
load...)
