> Sometimes during the use of our webapplication the cpu of our server has extereme high load caused by geronimo which stays high forever untillI stop geronimo. I have created a thread dump when the cpu load is high (attached to this jira). Suspicious in this thread dump are multiple thread in the containsKey.
> As not all the access of the resourcesNotFOund map is not synchronized this could be the cause of the problem as this might result in a infinite loop when the contains method is called during a map resize.
