Maximum numbers of threads and heap size

java version "1.5.0_08" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_08-b03) Java HotSpot(TM) Client VM (build 1.5.0_08-b03, mixed mode) On a redhat 9 machine, I can get a maximum of 612 threads in tomcat when I start it with -Xmx1500M. Without a -Xmx param I get 3448 threads.

Changing heap size

Hello, I am using Java2 on RH6.0. I have developed an GUI application using Java. Now it runs out of memory at some places. So I am increasing heap size with the help of -Xmx and it works fine. But, I have to do this every time I run application. Is it possible someway to permenantly change the

Re: Maximum Heap Size

I don't know if this has been mentioned but we developed a multi-threaded app and had OutOfMemoryError problems similiar to yours. The culprit was the 1.1.5 jdk (had thread memory leak problems). After upgrading the jdk our problems went away. Robert Mehrdad Jahansoozi wrote: > This is usual

Re: Maximum Heap Size

This is usual in multithreaded programs There are two solutions to these sorts of problems 1) Limit the number of threads to 5 at any time. 2) Write the data on a temporary files and read it later. Which one is a mater of time ( speed ). If you are reading over a network, pipe the data directly

Maximum Heap Size

Is there any way to get the maximum heap size from inside java. I though that Runtime.totalMemory() would return that, but it does not. I current am running one vm with -mx50m and totalMemory() is returning 5242872, which is about 5mb not 50mb... unless I am totally crazy. I am running into a
