Summary: 0001782: Watchdog uses too much memory
Description: (rep by M Schmidt)

I know in 3.1 you switched to a Java watchdog process.
Unfortuantely, this process seems a bit heavy. Its using 200M resident
memory and 1500M virtual. Is there a way to slim that puppy down a
bit? The nice thing about the perl script was that it didn't use much
memory.

Maybe we haven't been aggressive enough in trying to reduce the
watchdog's footprint. Here are the watchdog-arg values we're using.
Can we trim this back even further?

<watchdog-arg>-Dcom.sun.management.jmxremote.port=9003</watchdog-arg>
<watchdog-arg>-Dcom.sun.management.jmxremote</watchdog-arg>
<watchdog-arg>-Xmx64m</watchdog-arg>
<watchdog-arg>-Xss256k</watchdog-arg>
<watchdog-arg>-XX:MaxPermSize=25m</watchdog-arg>

It does seem to be keeping
a lot of threads alive (possibly in order to support the JMX remote).

Reduced defaults and number of threads, but really this is a Java runtime issue, not primarily a Resin issue.
