Multiple JVM instances stop simultaneously.
We have a customer running JRE 1.5.0_8 on a Windows 2003 Server.
We have multiple java applications running in the background on this server. We keep having an intermittent problem where all of these java applications shutdown at the same time (I'm talking within the same second). It apparently is somewhat of a clean shutdown because our shutdown hooks are running; however, these programs should not be stopping. There are no dumps being created by the JVM. It happened twice yesterday, but the day before did not happen at all.
These applications are spawned into the background by a windows service we wrote and this same service will restart the application automatically when they stop in this fashion so the customer really has not noticed. Sometimes when the applications are restarted, they will stop immediately and our service will start them again and they stay running.
We have logs running on these applications and there is nothing in these logs that would suggest the applications should shutdown.
These same applications are used at other customers' sites and we do not have this problem. This is; however, the only site running 1.5.0_8, all of the others are running previous versions of the JRE.
I do not know what kind of Windows patches has been installed by the client.
