Nginx error.log filling with (61: Connection Refused) since 2.3.4

  • I've had a couple problems with pfsense since the 2.3.4 update related to /var/ filling up. Both times it's been a single message repeated over and over in /var/log/ngnx/error.log. I don't see errors accumulating while I'm watching, but suddenly there's 30MB of error.log, a spot check revealing only lines very much like below:

    2017/05/18 07:08:31 [alert] 32223#100183: connect() failed (61: Connection refused)
