Re: [Wrapper-user] RESTART not wanting to work

[Richard E. <rem...@ed...>]

If you are using JBoss and its logging to a file, then the wrapper will 
not see
the OOME error log message. You MUST also log (at least at the error level)
to the console for the wrapper to see the OOME error message.
We just discovered this truth. Restart on OOME used to work. Then someone
change the log4j.xml file (no longer logging to console). Then the JBoss
system stopped restarting on OOME. It took a while to figure out that
the left hand did not know why the right hand had set up the log4j in a
certain way.
good luck.
