I wanted to post this a while back, but had endless problems registering on the forum.
I also recently had this problem. In my case it was because the ERAServce service had stopped running. If I take a look at the logs:
tail -f /usr/share/tomcat6/logs/catalina.out
I see the following:
Jan 04, 2016 1:05:05 PM sk.eset.era.g2webconsole.server.modules.logger.FileLogWriter addItem

Check the service status:
service eraserver status
ERAServer is stopped
Start it
service eraserver start
Starting ESET Remote Administrator Server [ OK ]
Check it again
service eraserver status
ERAServer (pid 13936) is running...
And with ps
ps ax | grep ERA
1846 ? Ssl 53:26 /opt/eset/RemoteAdministrator/Agent/ERAAgent --daemon --pidfile=/var/run/eraagent.pid
13936 ? Ssl 0:09 /opt/eset/RemoteAdministrator/Server/ERAServer --daemon --pidfile=/var/run/eraserver.pid
I haven't seen the ERSServer crash more that the one time, but perhaps a feature request for ESET is to create a monitor service that checks if the required services are running and start them if needed.
