Subject Is there a possibility of Duplicate Entry
Date Wed, 28 Nov 2007 11:56:48 GMT
Hi,
 I am using JCS Remote Caching Server.

In the JCSAdmin.jsp, we are finding duplicate key
entries. The objects associated with the key are
different. Is there a possiblity that the Cache is
storing duplicate key entries? This is happenning for
one in a half-million entries.

What precautions should be taken to avoid this
situation??

The CLIENT config is:
**************************************
jcs.region.mycache=RC
