My GGS 22.214.171.124, Patch.v4 126.96.36.1990 all plugins green.
I found problem on Franson NMEA Service.
The first occurrence on 24th April 2014 at 01:22 local time, the Franson NMEA Service stop by it self (I check under Windows service panel).
Restarting Service from SiteAdmin\Service tab did not solve the problem.
Reboot the Server for first time also did not solve the problem.
The Franson NMEA Service in Windows service status Started, also on SiteAdmin\Service tab the status Running. But when I open VT Application, all vehicles status red.
I check the Server status, the RAM usage very low, The Franson NMEA service usage less than 200 MB, usually more than 1 GB.
Reboot the Server for second time solve the problem, I check the RAM usage for Franson NMEA service more than 1 GB. Checking on VT Application now all vehicle start updating with status green and yellow.
This condition not last for long (less than an hour) the Franson NMEA Service stop again. This time either re-starting from SiteAdmin\Service tab, or restarting from Windows service administration panel or rebooting Server unable to solve the problem.
Yes, the Franson NMEA Service status is started/running, but when opening VT application, all vehicles status still red.
Please help. Thank you.
