In Linux land, a seg fault in Tomcat is typically caused by a bug in Sun's 
JVM 1.3.  Try adding 'ulimit -s 2048' to startup.sh before the line calling 
catalina.sh.  The bug specifically has to do with how Sun's JVM handles 
memory when it sees 'unlimited' for a stack space in the Linux environment.  
Couldn't tell you the exact bug parade number, but it's posted at Sun's site. 
 I've heard it's fixed in JDK 1.4, but I haven't tried it.
