MSMQ: What can cause a "Insufficient resources to perform operation" error when receiving from a queue?

At the time the queue only held 2,000 messages with each message being about 5KB in size.

I had the same error message and the solution was simple.

There were a lot of messages sitting on various queues, and the storage limits had been reached. I went to:

  • Server Manager -> Features

  • Right clicked on Message Queuing

  • Selected properties

  • In the General tab un-ticked the storage limits

I was informed that services using MSMQ would be re-started, and then the error went away.

    Good instructions. Although I would still set a limit ... leaving it to become as "large as possible" gives the risk of filling up your hard drive. That might in turn cause even more severe errors than msmq's "Invalid resources to perform operation". – goamn Jul 21 '14 at 23:21

    True, though it's very easy to monitor hard drive space, and an IT department won't have to know about any other limits to be aware of. – Philip Aug 04 '14 at 10:11

    also accessible via `Computer Managment` -> `Message Queuing`, right click -> `Properties` – inwenis Sep 18 '17 at 12:55

From John Breakwell's Blog there are eleven possibilities:

  1. The thread pool for the remote read is exhausted (MSMQ 2.0 only).
  2. The number of local callback threads is exceeded
  3. The volume of messages has exceeded what the system can handle (MSMQ 2.0 only).
  4. Paged-pool kernel memory is exhausted.
  5. Mismatched binaries.
  6. The message size is too large.
  7. The machine quota has been exceeded.
  8. Routing problems when opening a transactional foreign queue (MSMQ 3.0 only)
  9. Lack of disk space.
  10. Storage problems on mobile devices
  11. Clustering too many MSMQ resources
  12. Too many open connections
  13. Computer name was longer than 15 characters
  14. Too many messages in the dead letter queue

I would check the version of your queue and the amount of connections (to and from) your queue open at the time of error. Any of those "could have" caused your error.

    It was the number of open connections. There was a bug where it would open connections in a loop and never close them. – Jonathan Allen Nov 13 '09 at 23:56

    What exactly is considered a "connection" to to the queue? I am working with the .NET managed API for message queuing, and the MSDN docs never mention the concept of 'connections.' – Dan Ling Feb 10 '14 at 23:21
  • In .NET, each `MessageQueue` object is considered a connection, so you need to `Dispose` them. – Jonathan Allen Feb 28 '17 at 06:40

I had too many failed messages in my outgoing queue. Check System Queues -> Dead-letter messages. I cleared this queue out and it worked fine again.

    This solved the issue for me as well, except it was the "Transactional dead letter queue" – Scott Mar 09 '15 at 03:37

If journaling is enabled, you will be storing copies of all messages removed from the queue, so you might also be hitting the MSMQ journal limit. Short term fix might be to purge the journals for the queue, longer term - disable journaling.

I encountered the same error, after checking the things mentioned above it turned out that it was the computer name that was causing the issue! It was longer than 15 characters, after I changed it to a shorter one the issue was gone.

For me, the problem was not the machine that hosted the queue. It was the machine that was sending the message to the queue. I noticed that the "Outgoing Queues" on the source machine showed large numbers of messages, which led me to MSMQ Messages Are Stuck In The Outgoing Queue. Reinstalling MSMQ on the source machine is what fixed it for me.
