Windows XP message queue full

By rfairchild ·
I occasionally get an error message saying "Windows message queue is full. Some messages may be lost." After clicking OK, everything seems to function correctly. I have not been able to pinpoint that the error is related to some specific thing that I am doing at the time. I am running Windows XP Pro SP2.

Hello...

As you may know, Windows uses a message queue to drive just about everything. Messages are added to the queue and later processed by event handlers. One simple example: A mouse button click involves button down and button up messages.

If the rate of messages being added exceeds the rate of messages being removed (processed) for an extended period of time, it is possible for the queue to become full. Windows will then discard some messages in order for the system to keep running. This appears to be occurring on your system.

Questions:

1. Which applications are you running?

2. Are you running any applications that you know require a lot of system resources such as CPU, memory, disk, or network?

3. Hardware: How much RAM? CPU speed?

4. Are you running any anti-malware programs? (virus, spyware, etc).
