Unable to kill Java process on Fedora Core 2

eblack · 09-10-2004, 09:38 AM

I have two instances of Tomcat(5.0.27) running on a Solaris dual processor blade server using Java 1.4.2. Seventy percent of the time, everything runs great, but occasionally one of the Tomcat/Java processes spins out of control and hogs most of the CPU resources. When that happens, I can't stop the process with a 'kill -9 ...' command, I have to restart the server.

I know it sounds crazy and my system admins didn't believe it until they saw it for themselves. I have a feeling that the JVM is intercepting the SIGKILL signal. Any help or direction would be greatly appreciated.

Yeah, im having the same problem killing the java process. I was running a jar file which is executable.

If the server/process has been started as root or as another user such as tomcat or www, you can only kill it as root.

Hi,

Im using root to kill the process but the process does not terminate. Under the
"grep psaux | grep java" command, the

pts/xxx -----is a----> ? sign

Thank u in advance.

if you have the command pidof available, to
pidof java|xargs kill -9

Hi,

it doesnt work. Any suggestions/other solutions to this problem? My cups service is having the same problem lately too.

I had forgotten about this post. I had the system admin try to figure out what the problem was and he wasn't able to fix the problem until he upgraded the kernel to 2.6.8. The same problem happened on another machine with FC2 as well and he upgraded to 2.6.9 to fix the problem.

Yeah, it's a big problem.

I managed to solve this problem by upgrading to Fedora Core 3.

Everything is solved now. ^_^

Thank u very much all.

I'm using jsdk 1.4.2_06.

I do encounter unterminated process,
but it's able to be terminated. (Very rarely however it happen)

1. Goto "System"->"KDE System Guard"
2. Choose the "Process Table" table. Click on the service that u want to kill.
