JBossDeveloper

hi manik

i got a massive number of ".. is newer .." error on read only transactions and even with only 1 user running - that is effectively no concurrency.

surprisingly the identical setup[i really mean identical because i copied the whole jboss dir with all cache settings and everything] seems to work on a different server in the cluster.

I upgraded from 1.3.0.SP2 to 1.4.1 to get some bug fixes and no I am getting the "in newer than" exception all over the place and I wasn't getting it before. I am using Hibernate 3.2 GA.

And this does not happen when you use 1.3.0.SP2? This is caused by concurrent updates on the node.

I rolled back to 1.3.0.SP2 and I am no longer experiencing the issue.

And is this under load only?
