The only thing I saw in stderr were NPE stack traces from the servlet
I'm running which did not seem to include any Tomcat code.
Keep in mind that I'm running Tomcat 8.5.12 so a more current source
repo is available at
https://github.com/apache/tomcat85/
With the file that you cited at
https://github.com/apache/tomcat85/blob/trunk/java/org/apache/catalina/core/StandardServer.java

Well, I took thread dumps on couple of Tomcat JVMs(which were not

But I don't see that for problematic JVM. It was stuck before
that(StandardServer.java:427) step.
at java.lang.Thread.sleep(Native Method)
at org.apache.catalina.core.StandardServer.await(StandardServer.java:427)
That's why I suspect JVM was not properly up and running. In fact, I
never saw a main thread in TIMED_WAITING waiting state. Again, I might
be wrong. :)
Thanks!
