I’m not sure what this could be, and I think running Discourse on 1GB of memory plus 1GB of swap is probably below minimum spec at this point so I’d understand if this is outright unsupported, but I’m having a weird issue where my site goes down at exactly the same time every day (at around 2:48 PST) for five minutes or so. Trying to hit it in the meantime sometimes throws 429’s.
sshing into the server and eyeballing top when this happens shows that about half of swap has been released (suggesting that maybe something else is running on the server and elbowing out Discourse, but I don’t know what it could be, there’s nothing in cron for that time of day), and most of the CPU is consumed by a single postmaster process until it runs for a little over two minutes, is killed, and then everything gradually goes back to normal.
Any idea what’s up here? Been happening for the past several releases at least.
