Using UBBT 8.0.1 php 8.3.32
I am confused
Our UBBT forum has been around for 25+ years.
Nowadays I can see below example of error messages.
I use standard amount of connections 151 just like this forum and the developers.
If it's not a bug feel free to delete. The last days have generated lots of logs like below.
