I am running a benchmark (TPC-W) whick requires a setup of iPlanet Web
Server(iWS) and Oracle Database, and iWS is configured on top of jdk1.3.1
b-18.

When I try to profile jvm with -Xrunhprof:cpu=samples flag, it would
cause iWS to hang if the workload is very large and iWS is assigned to
more than 1 CPU on the multiple-processor server. It works fine if iWS
is only allocated onto a single CPU even if the benchmark workload is
very large.

I have attached 3 files:
truss.log - use truss to track the iWS process
pstack.log - log of pstack command on the iWS process
mpstat.out - output from mpstat
all outputs show that the processes are sleeping there and CPUS doing nothing
while the iWS hangs.

Please contact Steve Wilson (###@###.###) or me to see/reproduce
the problem. Setup for the benchmark is very complicate.
