Thread: Weird delays on pgsql-committers email traffic
For the last day or so, I've been seeing that commit emails suffer a noticeable lag, five minutes or more. Which is weird because traffic on other, higher-volume lists is not similarly delayed. Maybe it's something in the mechanism generating the mail, rather than the fault of the mailing list server proper. regards, tom lane

Hi! Yeah, there is a strange delay since approximately a day ago. It's in the outbound delivery from the commit messages. We are currently investigating where it's coming from -- we're seeing similar patterns from a couple of other hosts. The delay happens before it even hits the listserver -- that's why regular email sent to the high volume lists still deliver quickly. It's stuck in a transient delivery queue for reasons yet not fully figured out. Thanks for the report! -- Magnus Hagander Me: https://www.hagander.net/ Work: https://www.redpill-linpro.com/

What I noticed is that pushing to and pulling from the master repo has gotten noticeably slow. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services

It basically caused mails from auxiliary^non-primary mail systems systems (like gitmaster) to get put in the queue immediately (instead of being delivered) and only deliver on the next queue run(which in this case runs on a 300s/5m schedule)...
