Hi, I deployed the JSW for a server application a few weeks back and its been working well since. I'm running Java 1.4.2 (on Linux) and Wrapper (JSW) 3.1.0. But for the past two days, the wrapper has been stopping on its own every few minutes, due to an abnormal faileur of some sort. The log dump is as follows: DEBUG | wrapperp | 2004/10/16 04:09:55 | send a packet PING : ping INFO | jvm 1 | 2004/10/16 04:09:56 | Received a packet PING : ping INFO | jvm 1 | 2004/10/16 04:09:56 | Send a packet PING : ok DEBUG | wrapperp | 2004/10/16 04:09:56 | read a packet PING : ok DEBUG | wrapper | 2004/10/16 04:09:56 | Got ping response from JVM DEBUG | wrapperp | 2004/10/16 04:10:00 | send a packet PING : ping INFO | jvm 1 | 2004/10/16 04:10:00 | Received a packet PING : ping INFO | jvm 1 | 2004/10/16 04:10:00 | Send a packet PING : ok DEBUG | wrapperp | 2004/10/16 04:10:00 | read a packet PING : ok DEBUG | wrapper | 2004/10/16 04:10:00 | Got ping response from JVM STATUS | wrapper | 2004/10/16 04:10:00 | TERM trapped.

Shutting down. I'm not quite sure what could be causing this. I have configured the wrapper so that it restarts automatically after any abnormal shutdown of the JVM. Any clues to what's the problem and how should I resolve it. Thanks, Nick -- Nick Rice nic...@em... |
