at my NetXMS Server (Win10, MySQL V5.7.30, 16GB RAM) i see the follow event in the windows event log: 

InnoDB: Over 67 percent of the buffer pool is occupied by lock heaps or the adaptive hash index! Check that your transactions do not set too many row locks. Your buffer pool size is 16 MB. Maybe you should make the buffer pool bigger?. Starting the InnoDB Monitor to print diagnostics, including lock heap and hash index sizes.For more information, see Help and Support Center at http://www.mysql.com. 

Has anyone an idea what buffer pool size i have to use? On this machine is only NetXMS running and no other DB's.

Thanks in advance...
