runtime.exec stale process

[karine]

How can I kill the runtime.exec stale processes? I tried proc.destroy.. didn't work

Thanks!

I've seen this before (windows I assume). After calling destroy call exitValue. It will cause an exception, so catch it, but after that the process is gone (usually).

Don't know why it's this way sometimes, but it is.

I've had a couple like that, too.

What are you using Runtime.exec() for? There might be a better way, and it might be that you shouldn't be using Java for this at all.

you may need to try again doing kill by some other process which can identify and kill it....

I have axis 1.4 webservice running in tomcat 6.0.18. I have a Runtime.exec calling a C program. When my Java client is connecting to the web service to get data through the C program many times (50 times) the Runtime.exec hangs and creates stale processes. How can I avoid this?

thanks!

I am thinking of doing "ps -ef | grep processId" Unix command to identify and kill it but it will be a workaround. I was hoping to fix it so it won't create these stale processes and hang.
