Hi Folks,
I'm developing a driver for an LDAP server(OpenLdap
1.2.10). 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 mutex 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(4.0)by the way. Below is a trace of the functionality being called before the crash courtesy of GDB. Any help will be greatly appreciated.
Regards
Jimmy
