Hi, Rhys.Campbell---, I don't think so. The error "Too many connections" is issued when the number of connections reaches --max-connections value. So it's rather as if your vendor app is _not_ reusing connections, and opens new ones instead, so they keep piling up. Or may be you just have a high concurrent load.

Hello All,

We have a vendor app that attempts a large number of connections and creating the following error in the MariaDB logs (10.11)

Aborted connection 0 to db: 'unconnected' user: 'unauthenticated' host: 'connecting host' (Too many connections)

Could this error be cause by the vendor app reusing connections that have been idled out on the server side?
