Re: [Wrapper-user] JSW not restarting app with OS

[Christian M. <chr...@ta...>]

Hello Dave,

thank you for your mail.

1) If you set the property IGNORE_SIGNALS=true in the script, the script
will tell the Wrapper to shutdown by deleting its anchor file. The Wrapper
should acknowledge the removal of the file and initiate the shutdown within
a few seconds, however. Is there any indication in your conf file on what
is delaying the shutdown so long?

2) please send me the 2 scripts you are using. I would like to make sure
the property "IGNORE_SIGNALS=true" is set correctly, because if it is set,
the Wrapper will not raise a SIGTERM to the Wrapper, but using the
anchorfile.
I assume that the script was running into a timeout and your OS simply
continued with the shutdown, killing your application forcibly. It should
have been started after the system got back up however, therefore I would
also see the value of APP_NAME in your script. APP_NAME is being used as
application name for in the init.d folder, e.g. /etc/init.d/myapp

Also what distribution are you running on?

Cheers,

Christian
