Title: processes leftover after quiting cadence
Post by jimmy on Apr 12th, 2005, 12:05pm
Hi,

I am using linux version cadence, icfb5.1.41. I found there are a lot of processes will stay in the system even though I quit cadence. Most of these processes seem to be related to java. Do you know how to automatically get rid of thsse process when I quit cadence. They actually use memory and make the machine slow.

thanks,
jimmy

Most likely they are the cdsdoc processes.

If you're running on Linux, you may be fooled into thinking that they take a lot of memory because there are a lot of processees which each appear to use so much memory. Java threads on linux actually show up as multiple processes, but the memory is shared, so it isn't really taking 10 times (or whatever) the amount of memory.

If it's cdsdoc, you can always type "cdsdoc" to bring up the GUI, and hit exit on the GUI. That will cause them to quit.

Regards,

Andrew.

Hi Andrew,

I found many of the produced processes are something like:

   20452 20431  0 00:01 ?        00:00:00 /usr/local/apps/cadence/current/tools/jre/bin/java -noverify -ms3m

Seems they are related to java. And the number of such processes are just huge.

thanks,
jimmy

Did you actually read my previous posting? I said that this is a consequence of how threads are implemented in Java on Linux.

For example, I just ran cdsdoc, and I have 22 jre processes showing up (I didn't do anything yet).

Regards,

Andrew.
