OFBiz cache settings

[Gautam Deb <ga...@in2m.com>]

We are using OFBiz as the framework for our application. Sometimes back 
we were facing some OUT OF MEMORY errors with OFBiz running in our 
Production Servers, which forced us to restart the server almost once 
every week. The solution we found for this is by optimizing the 
cache.properties file. Some of the entities for which we optimized the 
cache are -

entitycache.entity-list.default.PartyRelationship.maxSize=300000
entitycache.entity-list.default.PartyRelationship.expireTime=86400000
entitycache.entity-list.default.PartyRelationship.useSoftReference=true

entitycache.entity.default.ProductPriceRule.maxSize=1800
entitycache.entity.default.ProductPriceRule.expireTime=86400000
entitycache.entity.default.ProductPriceRule.useSoftReference=true

This solved the OUT OF MEMORY issue completely, but now we are facing 
some other issues as a side effect of these settings, we guess. The 
issue is like -

[ServiceDispatcher.java:runSync:410 :ERROR] :: Service Error 
[createPartyRelationship]: Error running the simple-method: Error in 
simple-method operation [<create-value/>]: 
java.util.ConcurrentModificationException<br/>null

Any pointer will be helpful.
