MSMQ Service Shows 100 Percent CPU Usage at Startup (269803)


The information in this article applies to:

  • Microsoft Message Queue Server (MSMQ) 1.0
This article was previously published under Q269803

SYMPTOMS

When you use Performance Monitor in Microsoft Windows NT 4.0 to track CPU usage, it reports that Microsoft Message Queue Service (MSMQ) is using 100 percent of CPU resources at startup.

CAUSE

When target journaling is enabled, and messages that were sent using a Direct=TCP format name are received, a copy of the message is placed in the journal for the target queue. Upon restart, the local Queue Manager sees these messages as not being local and attempts to send them to itself (because of the TCP/IP address). This can either result in an fatal exception error or cause CPU usage to go to 100 percent.
