A long shot, but if you are running RHL9 you might try this, as mentioned in the TC 5.5 release notes at http://tomcat.apache.org/tomcat-5.5-doc/RELEASE-NOTES.txt :
================ Tomcat on Linux: ================ GLIBC 2.2 / Linux 2.4 users should define an environment variable: export LD_ASSUME_KERNEL=2.2.5 Redhat Linux 9.0 users should use the following setting to avoid stability problems: export LD_ASSUME_KERNEL=2.4.1 Apparently the problem is that RHL introduced the "Native Posix thread library", see here (find "NPTL" in the page to jump to the explanation): http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/release-notes/x86/ I've noticed it handing a JVM that does a lot of socket access from the command line. The VM just stops dead without reporting anything.
