I’m testing out Render’s managed redis instances with a free tier instance (50 maximum simultaneous connections) and I’m noticing something weird.
Looking at the “active connections graph”, it seems to go up and up, and then when it reaches 50, it drops all the way back down to 0, and claims there are 0 active connections, but it’s just not true - I’m actively reading and writing from redis from terminal and from my WebApp.
With very specific bug reports like this, it’s usually helpful for us to be able to take a look at your service details.
If you don’t want to share these publicly, I’d suggest opening a support ticket from the dashboard, including as many details as possible, such as timeframes when you experience this, including a time zone.
