I can't analyze every single queries, it's a mysql hosting server with more then 90.000 tables and 16GB RAM.

sometimes i'll get tons of quries running for 200-300 seconds and many other in locked state. Usually, the long running queries are always write queries and every other select is stuck in locked.

Even a single update query like:

UPDATE table SET field1 = 'test' LIMIT 1

is running for 300 seconds.

A single query on a database can lock every other queries on others database?
