Please let me know if you still have this issue with new version {{2.20}} of Surefire.
If you could measure the GC pauses {{via -verbose:gc}} I would really appreciate your help. Thx.

> This issue happens because surefire kills the forked container if it times out waiting for the 'ping'.
> In org.apache.maven.surefire.booter.ForkedBooter class there is hardcoded constant PING_TIMEOUT_IN_SECONDS  = 20 which is used in the following method:
> {code}
> private static ScheduledFuture<?> listenToShutdownCommands( CommandReader reader )
>     {
>         reader.addShutdownListener( createExitHandler( reader ) );
>         AtomicBoolean pingDone = new AtomicBoolean( true );
>         reader.addNoopListener( createPingHandler( pingDone ) );
>         return JVM_TERMINATOR.scheduleAtFixedRate( createPingJob( pingDone, reader ),
>                                                    0,PING_TIMEOUT_IN_SECONDS, SECONDS );
>     }
> {code}
> to create ScheduledFuture.
> In some of the cases the forked container might respond a bit later than it's expected and surefire kills it
> {code}
> private static Runnable createPingJob( final AtomicBoolean pingDone, final CommandReader reader  )
>     {
>         return new Runnable()
>         {
>             public void run()
>             {
>                 boolean hasPing = pingDone.getAndSet( false );
>                 if ( !hasPing )
>                 {
>                     exit( 1, KILL, reader, true );
>                 }
>             }
>         };
>     }
> {code}
> As long as we need to terminate it anyway, It would be really helpful if the problem could be solved making the PING_TIMEOUT_IN_SECONDS  configurable with the ability to specify the value from maven-surefire-plugin. 
> It would help to configure this timeout based on needs and factors of the projects where surefire runs.
