JRE 1.3 core dump

[Ming-Wen Sung]

We are running a Java multi-threaded application using JRE 1.3.01 on HP UX-11 platform. We have all the required patches installed for JRE 1.3.01. This program runs fine on Sun Solaris platform. However, most of the time the process hangs on HP platform for unknown reason and occasionally core is dumped. The following is the call stack from the core file:

-->#0 0xc01f4020 in kill () from /usr/lib/libc.2
#1 0xc0191378 in raise () from /usr/lib/libc.2
#2 0xc01d19ac in abort_C () from /usr/lib/libc.2
#3 0xc01d1a04 in abort () from /usr/lib/libc.2
#4 0xc6b020e0 in report_error () from /opt/java1.3/bin/../jre/lib/PA_RISC2.0/server/libjvm.sl
#5 0xc6be43f4 in JVM_handle_hpux_signal () from /opt/java1.3/bin/../jre/lib/PA_RISC2.0/server/libjvm.sl
#6 0xc6be40dc in signalHandler () from /opt/java1.3/bin/../jre/lib/PA_RISC2.0/server/libjvm.sl
#7
#8 0x7d450770 in ?? ()
#9 0x7d4646f0 in ?? ()
#10 0xc0191378 in raise () from /usr/lib/libc.2

Can you help me to understand what it means, why it happens, and how to avoid it? Attached gives more detail information from core file. Thanks.
