We found a potential memory leak on Performance Management.
After upgrading to r3.7.x we see a major increase in memory utilization on the Performance Center server.
The server is also showing swapping activity per this sample:
total used free shared buffers cached
Mem: 94G 94G 349M 4K 58M 5.0G
-/+ buffers/cache: 89G 5.3G
Swap: 31G 8.9G 23G
Performance Management releases r3.7 GA through r3.7.4.
There is a problem with the performance schema that is enabled by default in the new version of mysql we are using in r3.7.x releases that now use MySql version 5.7.24
This is resolved in the r3.7.5 and newer releases per the following note in the Fixed Issues list.
To resolve the issue in the current systems we can take the following steps to disable the performance_schema setting.
