Thanks for the suggestion.
I understand that wal_sender_timeout should be increased. Experience has
shown that for status-interval=1s it is necessary to configure wal_sender_timeout
to 15 seconds.
Nevertheless I found out that if I call
pg_basebackup -h host01 -U dbuser -D
/var/PostgresDb --wal-method=fetch -w
(using fetch method instead of default
stream method),
pg_basebackup completes successfully.
Best regards,
Andrei

Yes, if pg_basebackup doesn't ping the server with a status interval
within wal_sender_timeout amount of time then the server is going to
think it's disappeared.

Sure- if they're both set to 1s, you're likely to still see the issue.
Networks take time and systems can end up being busy, so having such a
very tight timeout is, frankly, unlikely to work out all that well for
you regardless.
You could try setting wal_sender_timeout to 2s or maybe 5s and see if
that works better.
Thanks!
