Hi All,

I'm developing a multi-threaded app using MQSeries on HP-UX 11. In this application I see a very strange problem: an MQSeries function called from the main thread runs 100 times faster then the same function called from a new thread.

I've enlarged stack, tried different compile options, etc. Nothing helps.

Can anybody help me?

Best regards,
Mike

What is going on in the main thread while the MQ operation is going on in the other thread? Which MQ API call is it? Which thread is the MQCONN statement executed?

It's OK now. The problem was in the libraries list. Our configuration managers put libmqm.sl instead of libmqm_r.sl in the link statement.

Thank you for cooperation,
Mike
