We have the same problem we're using Jboss 4.0.4 with EJB3 RC9 with 1.5. jvm... but we NEED Clustering!!! is it possible to have Clustering without @Remote ejbs!?!?!?!?
i Found an interesting article on memory management/watch
with these info i see that perm gen leaks comes when the perm gen space is close to the limit whatever it is... we try with the default 64 mb and 128 mb and the problem shows up when we're close about 2/3 mb to the limit
i found a bug on:
it's for mustang(b39) version...
IMHO the most interesting workarounds is to launch the jvm with the params
that enable the permGen to be garbage collected
