First ever instance crash. Suggestions for avoiding this in the future?
!Friendica Support
I had my first-ever server crash of https://my-place.social. This is in syslog:

show variables like 'max_connections'; shows 151 max_connections.
I did: SET GLOBAL max_connections = 200;
I also edited /etc/mysql/mariadb.conf.d/50-server.cnf and set max_connections = 200
Is this too high? Too low? Did I do this the correct way?
Thank you!
Thanks!

•@Jerry on Friendica Not an expert but you should try to increase this value by at least doubling it.
Beyond your own users, your server is receiving requests from every other Fediverse instance your users are interacting with through their follows and followers, and their number will be ever increasing.

•Thanks! I just bumped it to 400. That's 4 times more than the default.
I hope 400 isn't exceeding some limit. I hope I did this correctly. 🥴

•What would happen if one were to increase this value by several orders of magnitude (e.g. 5,000 or 50,000)?
In other words, what are noticeable signs of a too high setting?
