MSMQ label buffer too small error RRS feed

  • Question

  • I periodically see a warning event ID 5740 in the Windows application event log from "BizTalk Server" that reads:

    The adapter "MSMQ" raised an error message. Details "The label buffer supplied to the API is too small."

    It doesn't appear to be causing any problems (no failed messages, suspended messages, or exceptions). There is no indication of whether this happened on a send or a receive port, let alone which port or message queue. I haven't been able to find a reasonable explanation online for what this means, let alone how to fix it. I'm not aware of us explicitly setting a "label" of any kind in BizTalk. Does anyone know what causes this?
