Hi guys, we're getting a lot of graphql / mysql connection errors. The dagster instance works, our devops says the database server is fine, but they show up randomly while browsing dagit. Could someone guide me what can be the problem here?

Hi Damian… this is intermittent? Is there a custom value set in the mysql config for the max number of connections?

@prha How can I check if this is intermittent? It shows up errors in ui then either refreshes automatically or I have to do it manually and works fine for a moment and again (but you can still launch jobs etc). Dagit and deamon are containers in docker but the mysql server is not. DevOps were saying that there are not any unusual restrictions.
Are there any other specific requirements for the connection to work properly with dagster? Maybe if I had the details I could ask them precisly.
