Hi Manik, Thanks for your reply and for pointing to the SP1, sorry it took me a bit to use the 1.4.0SP1 and reply, since I needed to recompile and deploy the AS. The last posted error vanished and I am able to use the cache now (partially). The before mentioned "[CacheLoaderInterceptor]" trouble is still there when using the SFSB (as expected, since this is a ejb3 thing and the way they use the cache, if I am not misstaken) and always knocks out the client. I did have some problems with the SLSB and the hib 2nd lvl cache, but I guess they are due to other causes. But just in case... What happened when I used the cache as a Hibernate second level cache was that in when using the provided config (for hib 2nd lvl cache, altered the TM Lookup form generic to JBoss) with: {Pessi, RepRead, INV-ASYNC} it seems to deadlock fast (at the "first" shoot) | in {Opti, RepRead, INV-ASYNC} it lead to an extreme load on the server even after the clients were done (this didn't stop and is in clustered and single server a problem). A second start of the clients then leads to more Cpu load and out of mem for the heap space. | | I guess I need to do some tweaking here. | Do you know if the EJB3 [CachLoaderInterceptor] related thing will be fixed in 4.0.5GA ? | | Thank you for your Help! | Sincerely | | marc View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3970046#...
