Public bug reported:
On Ubuntu 22.04 Pyzor crashes twice on startup most likely due to a
start before network is initialized as error reported is DNS related:
File "/usr/lib/python3/dist-packages/pyzor/client.py", line 116, in check
sock = self.send(msg, address)
File "/usr/lib/python3/dist-packages/pyzor/client.py", line 138, in send
return self._send(msg, address)
File "/usr/lib/python3/dist-packages/pyzor/client.py", line 143, in _send
for res in socket.getaddrinfo(addr[0], addr[1], 0, socket.SOCK_DGRAM,
File "/usr/lib/python3.10/socket.py", line 955, in getaddrinfo
for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -3] Temporary failure in name resolution
A guess of what is happening (but would need debug startup logs to confirm):
init system starts (probably systemd those days in Ubuntu)
init system parses startup files
init system decides to start networking in background
init system decides to start MTA (like exim, postfix, sendmail, ...) in
background
init system decides to start spamassassin in background (in parallel with
already running startup scripts)
init system finishes starting up spamassassin
init system finishes starting MTA
MTA delivers previously queued mail to spamassassin to process
spamassassin calls pyzor
pyzor bails out with error as networking has not finished starting up yet
(might be unrelated issue - why your network takes longer then usual to start?)
networking finally starts
MTA delivers (new) mail to spamassassin to process
spamassassin calls pyzor again
as network is now working, this and subsequent calls to pyzor work just fine
The issue is likely that step 5. (init system decides to start
spamassassin) should have been delayed until network startup is finished
(i.e. step 11. in example above), as spamassassin with network test
enabled (like pyzor) requires networking to be working beforehand.
