[Mailman-Users] Mailman stopped working, no changes on machine, with error log output

[Abel Wisman]

All of a sudden and with no reference to any error in any other log then
the mailman specific logs, mailman (running several lists) stopped
working.
Went through the entire q 3.14 and all checks out fine, yet this is
found in mailman/error.log:

Jan 12 00:14:01 2004 (1291) Delivery exception: (-2, 'Name or service
not known')

    return self.Present(mime=1)
  File "/var/mailman/Mailman/Handlers/ToDigest.py", line 254, in Present
    envboundary = mimetools.choose_boundary()

line 116, in choose_boundary
    hostid = socket.gethostbyname(socket.gethostname())
gaierror: (-2, 'Name or service not known')


Any help would be appreciated

Kind regards
