Hello,
Sorry for the delay, I’ve been testing a lot to make sure I gave the right answers based on what you asked.
No OOM messages, the 8GB limit was never hit. With all containers and with clamd / rspamd disabled.
I reinstalled on a different host platform, it worked fine, and I was pretty sure that wasn’t mailcow because otherwise I would not be the only one having some troubles.
I even installed it on a raspberry pi5 (which works fine btw, I almost left it there 😃)
From the logs (I saw a bunch, a loooot of info going through, but I took the time to analyse a 1h timeframe, with 3 or 4 freezes (mailcow came back to life few minutes after)) I didn’t find anything useful.
Then I cleaned all dns, all email from the same domain that would interfere with the configuration (even if it froze just after installation, with no configuration apart the one in the .env file)
Sadly for this topic, after 3 or 4 reinstallations on the vps, it seems to be stable : no freezes since 30h (I monitor every minute port 443 & imap)
That’s a win for me but apart a reinstallation on a clean slate, I have no answer for me nor for you regarding those freezes.. !
