Notes/Domino 6 and 7 Forum : DSAPI Initialize Crashing HTTP on Linux

We have our shared library which we want to use as DSAPI filter for Domino on Red Hat Linux Advanced Server 2.1. Our library makes use of pthreads (a library of POSIX-compliant thread routines). Our this library is working fine with Domino 6.0.2 Web Server on Solaris. But when we load this library on Linux, just after loading the library the web server crashes.

The Console Output is
stackpointer=0xbffb4a88
Stack base = 0xbffebdd4, Stack size = 226700 bytes
Fatal Error signal = 0x0000000b PID/TID = 17366/1024

When Looking at output file generated by NSD(Notes System Diagnostic), the stack trace of the http process is

prog: /home/agent6/Domino602/lotus/notes/latest/linux/http pid(s) : 17366

Any Inputs about the possible cause of the problem and how can this be resolved ???
