Re: Tomcat unexpected shutdown on Solaris
Hi, We are experiencing similiar problem, and we have added a shutdown hook to JVM : Runtime.getRuntime().addShutdownHook(new PrintStacktracesOnShutdownHook()); and used Thread.getAllStackTraces() to get all stack traces and printed them out. Finally it occured that process really did got SIGHUP signal. Hope it helps, let us know what happened after that.

Tomcat unexpected shutdown on Solaris
Dear List: I have installed Tomcat 6.0.26 with Java 1.6.0_20 in a Solaris 5.10 OS virtualized machine. Everything works fine, but unexpectedly Tomcat shutdowns gracefully. In catalina.out I see the following lines logged: Jun 16, 2010 7:07:18 PM org.apache.coyote.http11.Http11Protocol pause INFO: Pausing Coyote HTTP/1.1 on http-9080 Jun 16, 2010 7:07:19 PM org.apache.catalina.core.StandardService stop INFO: Stopping service Catalina Jun 16, 2010 7:07:19 PM org.apache.coyote.http11.Http11Protocol destroy INFO: Stopping Coyote HTTP/1.1 on http-9080 I also change the shutdown port from 8005 to 9005. I have checked all the logs and there is no exception displayed, no error, nothing. I look for an error file from java, but there is no one. It happens randomly. Sometimes the Tomcat works for large periods of time, sometimes it shutdowns 5 minutes after it has been started. Does somebody has any idea? Any suggestions will be greatly appreciated.
