The slave server in our environment slowly starts increasing the memory.
According to MySQLTuner the sql server should consume max 5.8GB Memory of 8 GB total.
As you can see in the attached pictures it seems to be a memory leak.
Other slave servers with the same configuration only consumes nearly 1 GB of 8GB total.
Engine is MyISAM.
OS is Ubuntu 20.04.
Looking forward to your help.
