MSMQ Deadlock in QM on Multiprocessor Routing Server with Connector (272202)


The information in this article applies to:

  • Microsoft Message Queue Server (MSMQ) 1.0
  • Microsoft Message Queuing 2.0
This article was previously published under Q272202

SYMPTOMS

When you use a multi-processor computer with an MSMQ connector application, the MSMQ service may become deadlocked. While the service is running, no MSMQ message traffic to or from the service is seen. If MSMQ Explorer is started, it stops responding (hangs) until the MSMQ service is stopped, and messages on other computers that send to queues on the affected computer accumulate.

CAUSE

An incorrect setting of a critical section allows for an internal resource deadlock for the MSMQ Queue Manager.
