I suspect in this case that some other process on the Linux system is starting to make use of the RTP ports which are expected to be used by HMP. Thus there is some conflict with another process as we see rtp open socket failures in the messages files.
You probably want to explore if another process running on the system is using ports in the HMP range (49152 - xxx) where xxx is the number of IP ports x2 in your license.
