Tibor17 commented on issue #231: Failsafe: Killing self fork JVM. PING timeout elapsed. URL: https://github.com/apache/maven-surefire/pull/231#issuecomment-485878074 @shark-horse The parent process won't be 100% bulletproof. The Heap grows slowly with small memory increments because there is only test statistics of a test class kept in memory, and logs are flushed to the file system and not kept (buffer size of 1 MB per test case). The worst is when the old parallel GC algorithm reclaims e.g. 12 GB sporadically. The question is how long it would take - max 30 seconds.
