unit и его лог

[Anton Kiryushkin]

Здравствуйте.

Подскажите, пожалуйста, как правильно читать лог unitd:

2019/06/15 23:08:18 [info] 890#1012 *959 shutdown(182, 2) failed (107:
Transport endpoint is not connected)
2019/06/15 23:08:25 [info] 890#1011 *1008 shutdown(182, 2) failed (107:

2019/06/15 23:09:21 [info] 890#1013 *1266 shutdown(180, 2) failed (107:

2019/06/15 23:10:25 [info] 890#1007 *1493 shutdown(187, 2) failed (107:

2019/06/15 23:11:14 [info] 890#1007 *1769 shutdown(179, 2) failed (107:
Transport endpoint is not connected)
2019/06/15 23:11:18 [error] 890#1007 *1782 send(180, 7F1195A6AF80, 1283623)
failed (32: Broken pipe)

Тут есть info и error. Верно ли, что info это про то, что запрос
завершился, все хорошо, просто ответ был отправлен клиенту. Про что error?

Попутно, можно ли keepalive использовать между nginx и unit?
