Hello,
I'm running a quite "memory-expansive" algorithm under Tomcat and I then got
the following error message :
> "Exception in thread "Thread-8" java.lang.StackOverflowError"
The expansive algorithm is a recursive one.
What is done is :
- (1) launch a servlet, retrieves user's parameters for the algorithm
- (2) launch a thread (my class extends Thread), corresponding to the
launcher of the high-cost algorithm
- ...
The fact is that when I ran the algorithm on my computer (a mac OS X, 1.25Gb
RAM) with the same test data, I had no problem and had no need to customize
JVM memory options
At this time, the algorithm was not implemented as a thread.
As I'm now deploying this on a server (mac OS X, 4Gb RAM), it has become a
thread launched by a servlet.
I now always have StackOverFlow exceptions.
I have already tried to customize JVM memory options with the following line
in my ".profile" file :
> export CATALINA_OPTS="-server -showversion -Xmx512m"
But I always have the same error message.
Can anyone help me ?
Thanks a lot
Regards
Benoit V.
