sendmail 8.12.7 squawking after MS 4.11-1 upgrade

[Steve Campbell]

Folks,

Was there ever a definitive solution to this problem?

I am running MailScanner-4.05-3 on a Tru64 system with sendmail 8.12.6, and I
see the error. For example:

sendmail[176424]: File descriptors missing on startup: stdout, stderr; Bad
file number

If, as someone suggested, there is a "leak" of file descriptors, then that is
what should be fixed.
