Hello together,

we have recently migrated our data from a MySQL5 instance to MySQL8 and also added more resources.

The specs of the old server are:

* 1 vCPU, 3.75 GB Memory, 84 GB SSD

The specs of the new server are:

* 2 vCPU, 7.5 GB Memory, 84 GB SSD  

The old server was at its limit but very stable. For example the memory usage was always very high but it never crashed:


The new server is a totally different story.

It crashes very often. The memory increases until it reaches the maximum and then the server crashes. In the logs we see nothing except a few bad queries that we had before and are about to optimize and the log output that mysql has been started.


We have no good idea and plan what to do at the moment.
