  • LLP Listener - HL7 message received in two parts

    I have the attached channel with an LLP Listener & a FileWriter. It works fine for smaller messages. But the larger HL7 messages are arriving in TWO parts; just chopped halfway ramdomly. So most cases the second part of the message is erroring out as it is not a complete message. Smaller sized messages do arrive fine. (by large messages I do not mean huge files, just 3kb ASCII files - multiple lab tests in one order)

    Please help me out. RequisitionsChannel.xml (23277 bytes)

      I imported your channel into a Mirth ver 1.6. Since the channel was created in a ver 1.5, the process suggested that some of the channel properties may not be the same. I let it automatically convert the properties.

      After a couple of minor changes to make things work on my box, I sent some 1k sized ORM-1 messages to the channel source port. The messages flowed through, were transformed and filed in the appropriate folder.

      I padded one of the messages with a total of 41 NTE segments so the file size would be 3k. I sent it a couple of times and it flowed through properly.

      As stated in the beginning, I am not running the same version Mirth you are testing with and this difference may be the cure...or, as the dialog box indicated when the channel was imported, our channel properties may have ended up different.

      I'll take a look at the channel file you attached and what the resulting channel configuration looks like and post what I find, if anything.

        This issue is one I believe I fixed in 1.6.0. The defaults in LLP listener (with the strict LLP validation) should not split messages anymore. Please try 1.6 and let me know if it works for you. Also, you should generally use strict llp validation unless you have problems with it.
