Ofbiz Cache issues

We are getting major caching issues in production. Most of it occurs
in LRUMap class. Following is the error that we just got:

2007-08-20 15:21:42,854 (TP-Processor67)
[ServiceDispatcher.java:runSync:387 :ERROR] ::

We had modified the cache settings for ProductPriceRule,
ProductPriceAction, ProductPriceCond to have a max size and
useSoftReference as false. Could this be a problem ?

Any help would be appreciated. Please reply back if anybody has any ideas on it.

Thanks,
Pradeep

Most of the effort required to fix this bug will be in finding a way to reproduce it.

Do you have any ideas on this based on where you are seeing it?

Also, which revision of OFBiz are you running on, and what changes have you made to the code or configuration?
