winbindd panic

[Herb Lewis]

I'm getting
[2007/05/08 20:20:20, 0, pid=3626] 
freebsd_46_i386/debug/build/samba/source/nsswitch/winbindd.c:add_fd_event(522)
PANIC: assert failed at 
freebsd_46_i386/debug/build/samba/source/nsswitch/winbindd.c

because of the following code

#ifdef DEVELOPER
                 SMB_ASSERT( match != ev );
#else
                 if ( match == ev )
                         return;
#endif

What is this code supposed to be doing? The call is comming
from the function fork_domain_child
