Hi Folks,

I'm developing a driver for an LDAP server. The driver functions are being
called 
from a multithreaded process with only 1 thread running. My LDAP functionality
has no
multi threading support as I have wrapped the functions with mutes locks. When I
unit
test the functions all is fine but when a process is kicked off from the Web
front 
end it causes a core dump with a SIGCHILD. I am using the Netscape SDK by the
way.
Below is a trace of the functionality being called before the crash courtesy of
GDB.
Any help would be greatly appreciated as things are going live on Monday!!.

Regards 

Jimmy
