[Wrapper-user] Disabling JVM ping

[Clement, N. <ncl...@qv...>]

Hi,

I've been using wrapper 2.2.9 and have found that it sometimes restarts the
JVM incorrectly under heavy load.  I have set wrapper.ping.timeout to 0, but
it still restarts the application with the following messages in the log
(note these occur a few seconds apart - i have trimmed the irrelevant parts
of the log):

Wrapper Process has not received any CPU time for 123 seconds.  Extending
timeouts.

The Wrapper code did not ping the JVM for 40 seconds.  Quit and let the
wrapper resynch.

Wrapper Process has not received any CPU time for 57 seconds.  Extending
timeouts.

JVM exited unexpectedly.

Is there a way to completely disable the pinging/automatic restarting
functionality? - it seems to be causing us many more problems than it could
solve.  Our JVM is quite stable and we have experienced no hanging problems
at all.

Here is the wrapper.conf file:
