MQ_ERROR_INSUFFICIENT_RESOURCES

MQ_ERROR_INSUFFICIENT_RESOURCES means that Message Queuing could not obtain resources needed to complete the operation. Microsoft lists insufficient memory as an example, and the operation fails rather than completing partially.

How to investigate

  • Check memory pressure, process limits, queue-manager health, and recent service or system events at the time of the failure.
  • Avoid uncontrolled retry loops, which can worsen resource exhaustion and obscure the first failure.
  • Retry only after the underlying resource condition has been resolved or capacity has been restored.
