Hi all, The JVM for the main process of our application (-Xmx1600M) was restarted by the Java Service Wrapper today after pinging with no response from the JVM for 10 mintues (as configured). I can't for the life of me work out why it was hung though - there were no exceptions in either the JSW log file nor the application's log file. Moreover, when the JSW tried to get a thread dump on exit, it failed. Here's a snippet from the log file: ERROR | wrapper | 2004/02/17 12:02:55 | JVM appears hung: Timed out waiting for signal from JVM. STATUS | wrapper | 2004/02/17 12:02:55 | Dumping JVM state. DEBUG | wrapper | 2004/02/17 12:02:55 | Sending BREAK event to process group 336. ERROR | wrapper | 2004/02/17 12:02:55 | Unable to send BREAK event to JVM process. Err(6 : The handle is invalid. (0x6)) ERROR | wrapper | 2004/02/17 12:02:58 | Java Virtual Machine did not exit on request, terminated Before this was just 10 minutes of pinging without response from the JVM. I know that noone can tell me what happened, but does anyone have some ideas on where to start looking (ie make the haystack smaller so that the needle is more obvious!). Regards, Paul Casanova |
