This caused the System. MessageQueueException: Insufficient resources to perform operation error as the storage area was full after few days.

How are you processing messages? Are they received from the queue or just peeked? If you receive a message, it will be removed from the queue and no longer count towards any quotas. The 6 hours you refer to is for clearing up empty storage files. You can also purge queues programmatically.

Purging the queues will not free up your. MQ files though. When a message is deleted from a queue, the space is still used up in the. To actually free up the space, MSMQ has to go through a cleanup process to garabage collect the space and throw away the unused.

You can also force a cleanup programmatically. If you are running MSMQ 3. If you run the script and the number of bytes reported is low, the Tidy should free up your 5GB.

When the Message Queuing service is still running you must determine which queues contain the built up messages. You may 1. Manually examine the queues using the Message Queuing 2.

Use Performance Monitor. You will be able to see the total number of messages in each queue. After identifying where the messages are accumulating, determine why the messages are building up.

The cause could be that messages in the outgoing queue cannot reach their destination, an application responsible for receiving messages has stopped responding, or perhaps messages in the journal or dead-letter queues have been forgotten.

Depending on where the messages are building up, you can delete them as required. When Message Queuing 2. You perform a backup of the Message Queuing configuration using a. Restart the server by using the 3GB switch in the Boot. The 3GB switch will increase the amount of addressable memory space allocated to each process.
