It probably depends on what's in your configuration.  My first guess
on how to find out would be to look to see if you can possibly use
strace or gdb or something to figure out what system call is failing.
You might need to temporarily add DisableDebuggerAttachment 0 to your
configuration file to allow you to attach a debugger.
