I was having an issue where SEPM 12.1.4 was not receiveing the latest updates. I created a forum thread (https://www-secure.symantec.com/connect/forums/sepm-not-getting-latest-virus-definitions) to get some advice and it was suggested that I move the DB from SQL express to full blown SQL. I did that and initially there were no issues. I was able to login to SEPM, lauch live update, get the version in SEPM to match the latest live update version. Then I restarted the server and tried to lgoin to SEPM again and it failed with "failed to connect to the server"
Checked the server services and found the Symantec Endpoint Protection Manager service was stopped. I started it, but about a minute later it would stop and the Application Event Log said "The Java Virtual Machine has exited with a code of -1, the service is being stopped" with a source of "semsrv", Event ID "4096". Starting the service again and reboots of the server did not help.
Not really sure what I should try next. Any suggestions?
