> Broker hangs on loading the data store. Happens after using the broker for 10 hours in productive environment.
> In broker log the last entries we see is a bunch of loading kahadb debug entries.
> 2010-05-05 16:06:19,462 | DEBUG | loading | org.apache.kahadb.index.BTreeIndex | main
> But the broker doesn't stall completely. It is doing something with high cpu load. But it doesn't get the data store loaded. Even after a few hours it doesn't get finished (usually only takes a few seconds).
> I took a few jstack-dumps where we can see the broker being busy putting something into a hashmap.
> We have 2 brokers connected as network of brokers.
