Hi, 
We are using Hibernate 3.0.3 with Synchronous replication cache (TreeCache)

        <!--
  |              Valid modes are LOCAL
  |                              REPL_ASYNC
  |                              REPL_SYNC
  |         -->
  |         <attribute name="CacheMode">REPL_SYNC</attribute>
  | 

we have 2 Servers, in each server, I have a lot of message similar at

When the servers are started the application is fast, after 2 hours the 
appliacion begin
to become so slowly. Realy I don'd why happed that. Somebody can say something 
to me on those errors?
