Permission checker errors under high load

[ts si, geändert vor 14 Jahren.]

We are currently facing a lot of problems with the class PermissionLocalServiceImpl under high load situations.
Our installed version is 5.1.1 and runs in a clustered environment on WAS 6.1

The full trace we are getting in the logs is attached below. The null pointerexception seems to come from the permissionCheckerBag variable. We have been diving into code but couldnt find the reason while it reaches with an empty value.

Any help will be extremely appreciated :-D

There is an article on my personal web site - www.curltalk.net about tuning Liferay. That might help you out.
