Java Process

Hi, today our main online system (ES45 Tru64 5.1a) started running
extremely slowly, to the point where customers were having a hard time
accessing the system. At this time I noticed that there was a process
named "java" running one of the CPUs up to 99%, and staying there. I
did a ps -ef|grep java and two of the following line came up:

root 10731 1 0.0 May 17 ?? 0:02.11
/usr/opt/java118/bin/../bin/alpha/native_threads/java -x2m
authentication/server/AuthenticationServer

The second one looked the same, but obviously with a different process
ID. Anyway, we looked at all the other servers, and they each only had
one of these "java" processes running. So we decided to kill the one
process that was chewing up the CPUs and everything came back to life
immediately. I was just curious as to what this process does, why it
might have shot up to 99% CPU usage, and whether or not it was a good
idea to kill it (everything seems to be running as usual). This is not
a web server, and doesn't even have internet access at all--and other
than that, I'm not familiar enough with Java to know what else might use
it. Thanks in advance...
