I have been running Tomcat in production on serveral Solaris servers with -Xss reduced down to 128K for years. This is for jdk 1.3.1. We have had no problems with exceeding the stack size.
I am not familiar enough with linux to get very specific.
First thing is to see if it is application related. Try load testing Tomcat using some example applications to see if it still has stack problems.
If there are no problems, then use OptimizeIt or JProbe to profile your application. That may give you some hints at what to look at.
Is Tomcat being run as the http server or do you have it behind apache so apache can serve static content?
You might try switching JVM's to see if that changes anything.
Just a few stabs in the dark. Others who use linux may have more specific ideas on how to troubleshoot this.

Hi - My apologies for posting on this but we really
need some help on this.
We have seen this problem showing up on Tomcat 4.1.24
(/JDK 1.4.2 from Sun/Linux) after running tomcat for a
few hours.
Fatal: Stack size too small. Use 'java -Xss' to
increase default stack size.
We have set the stack size to 1024k (and also 1536k)
and we still get this error. Heap size is -Xms/Xmx 1.5
Gb. We are running RedHat 8.x (Linux 2.4.18-19.8.0smp
#1 SMP Thu Dec 12 04:36:25 EST 2002 i686 i686 i386
GNU/Linu)
Not sure if this is an application bug (recursion) or
something to do with Tomcat. There is no other error
message/exception in any of the tomcat log files.
Is there a way to track this down by enabling verbose
Tomcat logging ? Any pointers will be *****very,
very***** helpful
Thanks
S Rau
