Hi,
I think we found a potential bug in MariaDB server 10.1.16, in production.
Checking the logs we observed that no application could execute sql. After we got max user connections limit reached.
The processlist showed that there were over 2500 transactions in different state having over 6 hours duration
I attached the innodb stats from the server, together with the server configuration.
Unfortunately no stack trace or anything is available.
