Hello,
We have a serious problem with our Servlet based webapplication.
In our website users can start calculations in background threads.
They can follow the status of the calculations in a monitor
with a refresh rate of 5 seconds.
However when we reach a certain number of threads (not always
the same number, approximatively 35, but sometimes less),
we get a message from the JVM **Out of memory, exiting**
The message comes from a routine in the library
Solaris_JDK_1.2/jre/lin/sparc/libjvm.so
The JVM crashes when this error occurs.
We tried raising the heap and the stack with -X options:
-Xss<size> set maximum native stack size for any thread
-Xoss<size> set maximum Java stack size for any thread
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
This doesn't help. We have 2 GB of RAM + swap, but this space
is hardly used. The error isn't a question of lack of (hardware)
memory. Can anybody help us?
PS: decreasing the number of threads is not an option!
Bruno
