Java HotSpot Virtual Machine

i am investigating a potential deadlock condition upon starting the Oracle 9i AS (OC4J v 1.0.2.2.1)
using jdk 1.4. the server starts, and serves static html pages, however it refuses to return
any request for a JSP page or one that results in java code being executed in the
internals of the server.

im running into this problem on a redhat linux machine, running kernel 2.4.2-2smp, glibc-2.2.4-19.
hardware is compaq dual pIII 1.4 ghz with raid 5 striping and 4 gigs of ram.

any known bugs with 1.4 dealing with either sockets or the java.security.SecureRandom
package?

here is the thread dump from the application server process:
