Re: [Wrapper-user] Wrapper restart delay

[Leif M. <le...@ta...>]

Grant,
    The Wrapper only imposes the 5 second delay, configurable by the
wrapper.restart.delay property.  If your application is taking 30 
seconds to restart
then something else is going on.   Try turning on debug output using the
wrapper.debug=true property.  You will then be able to see exactly what 
is going
on .

    The most common cause of slow restarts is that your application is 
not shutting
down immediately.  This should be obvious from the debug output.  If you 
have
any questions about how to read the debug output then go ahead and post 
it to
the list.

    Cheers,
    Leif
