too many java processes ???
When we run tomcat, it opens about 30 java processes and it takes
a lot (almost all) of our 128 MB memory. Is that supposed to be?
We are running it on linux.
Processes look something like this...

please let us know how we can limit so it doesn't use whole our memory...
thanks

Hi,
Are you using Multi-threaded Applications??? If so, this would be
natural...;-)
With the Linux Operating System... Threads are actually reported as
being processes...;-)
Try using top or ps -aux and add up the memory usage of the
processes...;-)
However, this does appear to be quite odd, if you have just run tomcat
and checked out the number of process running right away...;-(
What version of the Linux Kernel are you using???

If you are having any problems with memory you can set the amount of memory
it should consume by using these options with java command(on Linux). Add
add these options read the tomat.sh file.
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
