What to do when XCOM server becomes unresponsive.

Issue:

The XCOM Server listens on a port to be aware for incoming transfer requests. In Detail it is the Windows listener process, caxcgsvr.exe. That port is 8044 by default (and 8045 for SSL-transfers) but can be changed to a different port.
When your XCOM Server becomes unresponsive your Server cannot handle incoming transfers any more.

Environment:
XCOM for Windows.
Resolution:

A possible cause for the XCOM Listener becoming unresponsive is when multiple SSL transfers are received that exceed the "Maximum Clients Range" global parameter value. This will cause an subsequent remotely initiated SSL transfers to fail. In that case please apply fix RO88307.

Additional Information:

You can check if XCOM Server is listening by issuing this DOS-Command:

netstat -ano | find "8044"

This will show a string like this if the Port is responsive:

 "TCP    0.0.0.0:8044           0.0.0.0:0              LISTENING       1438"

and no string if not.
