I have a problem with a newly installed MySQL box:
When trying to access the database with multiple clients and a lots of retries, sporadically, connecting takes longer than 3 seconds. I only get this behaviour when I try to connect over tcp (no matter if the client is local or remote). If this state is reached, every connection, regardless of the port, takes 3 seconds.
I tried to reproduce this behaviour on another server, but neither the old database server nor the new slave show this behaviour (which to me doesn't make any sense, since master and slave are running on the same OS, the same patch level, the same database version, the same config...)
Searching the internet, I found a link to an email that describes exactly what I experience: http://email@example.com/msg02040.html, but I couldn't find any solutions.
Does anyone have any experience that could explain this?
Edit: Before anyone asks: it's not a DNS issue, we set skip-name-resolve as a default in every new MySQL installation.
