The debug message ("Closing session when complete at address") is printed all
the time so it should close the session. I've investigated a bit further and
I see that the problem seem to be that DefaultProducerTemplate holds a
SpringCamelContext which in turn holds an ArrayList which seem to contain
all MinaProducers that has ever been created.I've uploaded a screenshot of the heap dump: http://old.nabble.com/file/p27625230/mina_camel_retaining_resources.png mina_camel_retaining_resources.png /Johan Claus Ibsen-2 wrote: > > Hi > > Could you google that exception and see what other Mina users have > encountered. > > And you see this DEBUG logging when you send to that remote endpoint? > > if (LOG.isDebugEnabled()) { > LOG.debug("Closing session when complete at address: " > + endpoint.getAddress()); > } > > > > On Wed, Feb 17, 2010 at 3:27 PM, Johan Haleby <[email protected]> > wrote: >> >> Hi, >> >> I'm running into problems when using Camel (2.1 and 2.2) with Mina >> endpoints >> configured to disconnect the session after each received message.
