[Mailman-Users] Strange error

[Oscar Renalias]

I've configured mailman successfully in a couple of Linux machines, but
now I'm trying to configure Mailman 2.0b6 under a SunOS 5.6, and when
running the wrapper, and after solving the common "Unknown mailer error
2", and I get an error I had never seen before:

Oct  3 11:28:02 my_machine sendmail[9396]: LAA04695:
to="|/home2/users/mailman/mail/wrapper post test", delay=00:23:42,
xdelay=00:00:01, mailer=prog, stat=Operating system error: Error 0

Any idea of what does "Operating system error: Error 0" mean?

Thank you in advance.
