Was on vacation, so I had a cron job restarting the service at 12 PM (noon) every day while I was away. This automatic service restart allowed the PMS service to run without any issues while I was away.
Upon my return, I removed the cron job, and I upgraded to Version 1.16.3.1402 on July 28, and began to gather statistics again.
The service required a manual restart on the evening of July 30, as the system was all out of memory.
It appears that the service crashed and restarted on the morning of July 30 and the evening of July 31.
The service required a manual restart on the morning of August 2, as the system was out of memory again.
