Environment

Release : 11.6

Component : XCOM Data Transport for Windows

Resolution

XCOM Support tested the same "xcomtcp -ping" commands on 2 different base r11.6 20035 SP03 installations and did not see the problem.

If the XCOM service process xcomd.exe had stopped abnormally then the log file should not be recording any more messages.
If support deliberately stop the xcomd.exe process from the Windows Task Manager, the listener process caxgsvr.exe remains running and thus handles the "xcomtcp -ping" command TCP/IP connection but returns the same XCOMN0469E error to the command line. However as expected no messages are added to the xcom.log file.
XCOM Engineering could only recreate similar error if there were some mixed XCOM version binaries involved.

A complete clean-up/uninstall of previous R11.6 SP02 install was done including removal of the XCOM directory structure & cleanup of XCOM registry entries.
After a new base install of 11.6 SP03 the problem did not re-occur.
