[openamq-dev] amq_server on AIX with amq.topic exchange crashes after 60K+ messages

[Dmitri Tsyganov]

Hello,

I am running release multi-threaded version of amq_server (v 1.2c3) on
IBM AIX 5.

I am using a client (running on Linux) to post messages to a topic
exchange (amq.topic) with a routing key that looks like this:
	
	US.NASDAQ.STOCK.msft (last part - symbol - varies from message to
message)

I use another client application (also running on Linux), which
subscribes to topic exchange and receives messages.

Sender client send messages as fast as it can and receiver tries to read
them as fast as it can.

After successfully transmitting about 60,000 +- messages, amq_server on
AIX crashes. It crashes consistently in the same spot. 

Here is a result of error message I see on amq_server console:

Assertion failed: self, file  amq_content_basic.c, line 674
IOT/Abort trap (core dumped)

And here is core dump:

IOT/Abort trap in pthread_kill at 0xd0128470 ($t9)

Could somebody take a look at this and have an idea what may be wrong
there? I didn't notice any excessive memory usage on the server side. 

Thank you,

Dmitri
