SIGSEGV 11* segmentation violation

[manoj]

Hi all,
I am new to Linux/AIX...I have experience with Java programming on
Windows..I m trying to integrate a legary third party application in
my JAVA servlets/JSP based application.

This problem is testing my wits...and it is really bugging me a
lot...any help is greatly appreciated..

I have Apache/Jserv combination on my Linux ( RedHat 7.3 ) machine. I
have jdk1.2.2. My servlet uses some of the .so files (
libsmime3.so,libnpsign.so,libnpsign.so, libnpsign.so etc..)., this
servlet basically signs ( digital signature ) a file using a
certificate from Netscape browser certificate store. strangely When i
make a call to servlet first time it runs successfully, when i call it
second time it crashes my JVM..and throws a VM dump in error log file,
which looks like this:

SIGSEGV 11* segmentation violation
si_signo [11]: SIGSEGV 11* segmentation violation
si_errno [0]: Success
si_code [128]: unknown siginfo
stackpointer=0x403e85f0

could any one throw some light on what's going wrong? does it have
something to do with green threads and Native code used by .so files
on Linux..
plz feel free to ask for any more onfo...

Thanks in adv
