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.

Notes
(0002018) sam 06-06-07 11:38	(rep by R Ross) 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).

(0002020) ferg 06-06-07 17:02	Reduced defaults and number of threads, but really this is a Java runtime issue, not primarily a Resin issue.
