We are using JBOSS as appserver . We have placed metadata in cache using Hash Map and loading it when server is started. Cache is working fine for one hour . Problem is after sometime like 1hr,2hr inconsistently when we try to use cached object from Hash Map it is returning empty object or some other value which is not mapped to that key. It is misbehavior.
Please send me some info if you have any. I am desperately looking for help
