file descriptors on FreeBSD

[Craig Bates]

My file descriptor problem:
Dec  9 10:01:04 mx3 sendmail[39837]: File descriptors missing on startup: 
stdin, stdout, stderr; Bad file descriptor

disappears if I restart MailScanner every hour.  The problem hasn't returned 
for 2 days.  

Juilian, what does the parent process do?  Which bits of code should I look 
at?

Thanks,

Craig
