I take it you have not been able to reproduce the problem outside CI yet @kevinjwalls?

Have you been able to pinpoint anything about where or when the failures happen? OS version, kernel version, Docker version, anything else? I saw some notes about it in https://bugs.openjdk.org/browse/JDK-8341518, is OEL referring to Oracle Linux? Only ever failures on OEL 7, never on OEL 8?
