Subject java.lang.NullPointerException @ TransportConnection.java:325
Date Sat, 14 Nov 2009 13:15:31 GMT

I'm using Active MQ 5.2.0 on Ubuntu 8.10 Intrepid (64-Bit). I'm only using
TOPICs. I have about 30 users connecting to this one Message Broker over the
Internet using the STOMP flash/actionscript client library from codehaus.
The producer is written in C. Throughout the day some of my users are
complaining they are not receiving messages from the topic, as much as 1 in
5 messages. The server is throwing the NullPointerException below. I don't
have much money, but if someone helps me fix this by Monday or Tuesday I'll
paypal them a $25 bounty.
