Our server suffered an abend this morning and it was traced to the LH.NLM running. In 6+ years of running the NLM on this server, this is the first abend I am aware of in either LH.NLM or LHIPXSER.NLM.

I have been asked to see if we can track down what might have caused the problem. I have included most of the relevant information from the abend.log file, as forwarded to me by our server admins.

Has anyone seen this before or have any ideas?
