I setup to machines with brand new installs of RedHat 7.3 and latest
updates.  I'm running one as a coda server, and both as coda clients.

Installed packages:
kernel-2.4.18-10.i686.rpm (from RedHat)
coda-debug-client-5.3.19-1.i386.rpm
coda-debug-server-5.3.19-1.i386.rpm
coda-debug-backup-5.3.19-1.i386.rpm

RPMS built from source:
lwp-1.9-1.i386.rpm
lwp-devel-1.9-1.i386.rpm
rpc2-1.13-1.i386.rpm
rpc2-devel-1.13-1.i386.rpm
rvm-1.6-1.i386.rpm
rvm-devel-1.6-1.i386.rpm
rvm-tools-1.6-1.i386.rpm

When I originally had the below problem pop up, I though it may have been
related to an issue with the EXT3 filesystem, so I went as far as
reinstalling the OS from scratch on both client and server and starting over
with EXT2 partitions.  I'm running Apache Webserver and Caucho Resin App
Server on both machines, sharing the /coda filesystem.  Apache starts and
works fine, but whenever I try to start Resin, I get the following dump and
the Resin startup fails.  Anyone know what could be causing this???  This
happens on both machines.
