hello,

yesterday we had a strange behavior.

djigzo accepts all emails but did not deliver anyone.  
in the syslog i find entries like this:  
"......lost connection with 127.0.0.1[127.0.0.1] while receiving the initial  
server greeting"  
and later in the syslog many entries  
"connect to 127.0.0.1 .... connection refused"

i tried to open http-management interface, but i got this error message:  
(See attached file: check.htm)

has someone an idea what has happend and what can we do to prevent this  
behavior?

regards

I guess one needs the /var/log/djigzo.log to tell what is going on....

Somehow the Java Virtual Machine got stuck which normally should not  
happen (perhaps a JVM bug?).

Java wrapper which is used to start Djigzo 'injects' a Java process into  
the JVM and periodically checks whether the JVM still responds. Java  
wrapper itself is a Linux application (written in C). It detected that  
the JVM was no longer responding and tried to restart the JVM. Somehow  
Java wrapper was unable to restart Djigzo.

JVM appears hung: Timed out waiting for signal from JVM.  
JVM did not exit on request, terminated  
JVM exited in response to signal SIGKILL (9).  
Unable to start a JVM  
\<-- Wrapper Stopped  
--\> Wrapper Started as Console

You test that the wrapper process restarts Djigzo after an unexpected  
exit by killing the Djigzo java process (using killl -9)

If I explicitly kill the Djigzo Java process Djigzo is automatically  
restarted by the wrapper process. djigzo.log after killing the Djigzo  
process:

JVM exited unexpectedly.  
JVM exited in response to signal SIGKILL (9).  
Launching a JVM...

In your case the Java wrapper was unable to restart Djigzo so it seems  
that there were problems with your Linux system. The big question is  
what kind of problems.

Is there anything relevant in syslog or kernel.log?

Kind regards,
