Tomcat takes up too much memory
Hi,
I am attempting to run Tomcat 4.1.12 on an AMD 120 with 24mb of ram running linux 2.4.18 and when i startup Tomcat it spawns about 27 child processes each taking up about 62% memory (go figure how that works). Am i doing something wrong or is my machine simply too slow to be running Tomcat?
Thanks

Should tomcat use this much CPU?
Posted by Brandon Cruz <bc...@norvax.com>.
Should the CPU usage percentage in linux continue to increase as long as
Tomcat is running. On a 1G processor with 512M Ram, it seems that the
memory usage is 90MB and the CPU usage is around 32% for only one of the
many java processes I see by using "ps aux". Is this normal, does it mean
there is a problem with Tomcat, a problem with our application???

Dude can you read? Perhaps you should try it before you start bagging people

And can you tell me doctor why I still can't get to sleep?
And why the channel 7 chopper chills me to my feet?
And what's this rash that comes and goes, can you tell me what it means?
God help me, I was only 19

Yah, dang it! There you have 1,674% of memory being hogged by Tomcat. You
guys have this figured to the T. Kidding aside, I bet you are beginning to
think you might be making a mistake about what the 62% means?

Each tomcat process you see in top is a thread, they share memory, so all
together they use 62% of memory.
And yes, tomcat takes up a lot of memory. I definitely wouldn't try to run
it on anything less than 64mb of ram.

I would not say its too slow. I would say it does not have enough
memory. Upgrade your memory if you can.
