i was testing JFR with custom events using a mostly empty custom.jfc 
file and noticed a large amount of jdk.CheckPoint events in the 
resulting repository and dump files (both count and size wise) after a 
few hours of uptime (using JDK 14). I tried to explicitly disable the 
event in the profile config but it didn't help. It seems to be around 
8MB of jdk.CheckPoint events per day for a mostly idling app server.

Accessing the event with the jfr commandline tool or API didn't work 
either and I couldn't find any other information on it.

What is it for? Some implementation detail needed for the file structure?

best regards,
