This is very frustrating - there's nothing interesting in the logs either. it just dies.
Today when I was trying to restart it, tomcat restarted OK, but the R-GMA servlet would not startup, announcing cryptically:
2007-03-06 16:49:21,601 [http-8443-Processor23] WARN org.edg.info.ServletBase - Error processing servlet request.
org.glite.rgma.system.UnknownResourceException: Object has been closed: 77151190
What on earth's going on there?
Paul saved the day, using the tomcat manager interface to stop and then restart R-GMA. After that is was a bit happier.
I'll have to work out some nagios alarm or cfengine test for tomcat though - as it just hangs simple checks on the daemon's presence won't work. Grrr...
