Question

Insufficient Ressources in MSMQ after Feb 25 Windows Patch

Anonymous

After the windows Feb 25 (CVE-2025-21181) patch we get insufficient ressources error from message queuing saying maximum number of queues created is reached. The setup has not changed so what can be the issue?

We are creating and deleting many queues (basically one message queues).

Hi

Have you got a solution to this issue or is the solution to remove the february patch and later patches ? I think that we also have the same issue.

Hello,

Thank you for posting in Microsoft Q&A.

Based on the description, I understand your question is related to Insufficient Resources in MSMQ after Feb 25 Windows Patch.

MSMQ has limits on the number of queues and messages it can handle, which might be affected by system resources like memory and disk space. Check the system's resource usage and ensure there is enough memory and disk space available. You might need to increase the virtual memory or disk space allocated to MSMQ.

MSMQ has a maximum message size limit (typically 4 MB per message) and a total storage limit based on available disk space. Ensure that individual messages do not exceed the size limit and that there is sufficient disk space for MSMQ storage.

Have a nice day.

Best Regards,

Molly

We already checked all resources and tracked it down to the QueueCountLimit (the number of created queues). This is per default set to 10000 and we need more in the setup (always creating a queue, sending a message and deleting the queue). The system did not changed but there was the roll out of the mentioned CVE patch.

Can you confirm that there was a change in behaviour for this kind of usage?
