On test environment an upgrade from TIM 10.2 to 10.5.2 was successfully tested and then rolled back by uninstall of 10.5.2. and install of 10.2. However when trying to start the 10.2 apmpacket service it fails to stay up and apmpacketlog.txt file contains the following lines:
Running command "ps -ef | grep apmpacket " confirms that no apmpacket process is already running. Also these files created when an apmpacket is running do not exist: /var/run/apmpacket.pid /var/run/apmpacket/pid /var/run/apmpacket/serversocket It appears that the apmpacket process is checking something at startup and the result is indicating that something related to an existing apmpacket process still exists. It maybe something left over from the 10.5.2 uninstall and reinstall of 10.2.
