Hi We're running Resin 3.1.11 (soon to be 3.1.12 in the next servicewindow) in our production environment, and a few days ago we had an app that was restarted several times by the watchdog - with no apparent reason.
The watchdog-log contains this: [2013/02/08 11:17:46.478] WatchdogProcess[Watchdog[results],1] stopping Resin [2013/02/08 11:17:46.478] WatchdogProcess[Watchdog[results],2] starting Resin [2013/02/08 11:20:37.256] WatchdogProcess[Watchdog[results],2] stopping Resin [2013/02/08 11:20:37.256] WatchdogProcess[Watchdog[results],3] starting Resin [2013/02/08 11:23:24.221] WatchdogProcess[Watchdog[results],3] stopping Resin [2013/02/08 11:23:24.221] WatchdogProcess[Watchdog[results],4] starting Resin There was a lot of regular and normal activity in our apps stdout-log before and inbetween all the restarts, but nothing that - in our opinion - should cause a restart by the watchdog. The JVM log has no mention of problems (performing CMS and young generation GC as expected) and load on the server was also low - no automatic stacktraces were taken. We have been running with the same resin configuration, app codebase and OS software-stack for a long time, so we are quite baffeled, as this struck us as lightning from a clear sky. Is there any way of getting more verbose output about the watchdog and what it decides to do? We tried setting <logger name="com.caucho" level="fine"/> and restarting Resin completely (not just a restart of the JVM), but that did not seem to help. Regards, Jens Dueholm Christensen Survey IT
