I've had this happen a handful of times for me too; with both OpenJDK11 and OpenJDK8 w/JFR (I'm on Fedora 31 fwiw). I
can't recall seeing this with previous Eclipse versions when using the same JDKs.

At first I thought the crash was tied to something (it errored when I zoomed into a graph), but the later crashes
happened when idle.. usually in the span of 2 to 5 minutes. Nice find.
