Hi All,
I just noticed this on a server I administer:
04:37:09 up 196 days, 19:03, 3 users, load average: 1.02, 1.03, 1.00
167 processes: 165 sleeping, 2 running, 0 zombie, 0 stopped
CPU states: cpu user nice system irq softirq iowait idle

(Please view in a fixed width font)
As you can see, the java process is taking up 100% of one of the
available CPUs, while leaving the other three almost completely idle.
Why?
I can see 58 Java threads running (ps xam | grep [j]ava | wc -l).
Yes, the JVM is running in server mode - /usr/local/java/bin/java
-server <other stuff>
RHEL3 U4, Sun JVM 1.4.2_05. The server is an HP DL360 G4 with dual
Xeon 3.2GHz CPUs.
TIA,
Binand
