A user reported this to me, and I'm seeing it too: Hi all :) After mail/dovecot upgrade to v2.3.7 it seems something went wrong with stat-writer... IMAP and POP3 logs: Jul 12 19:45:34 mail dovecot: imap-login: Error: file_ostream.net_set_tcp_nodelay((conn:unix:/var/run/dovecot/stats-writer), TRUE) failed: Invalid argument Jul 12 19:45:34 mail dovecot: imap-login: Error:

After upgrading to 2.3.7_1 I get those errors every now and then. Running FreeBSD 12-RELEASE. Any idea what they may be?

...uld return data that is already buffered in memory. If there's nothing, it returns EAGAIN. The FS API's set_input_callback() can be used to set a callback function that is called whenever there's more data available in the buffer. Async output streams also work the same as non-blocking file_ostreams: write() returns the number of bytes added to buffer. When buffer becomes full, it starts returning EAGAIN. The ostream handles flushing internally the same way as file_ostreams does, although instead of using io_add(IO_WRITE) it uses FS API's set_output_callback(). If callers need to know when...
