There absolutely must be SOME way to detect WHY a #Java #Tomcat server would suddenly, after 6 years operation, spontaneously exit after 25-50 seconds of perfectly functional uptime and yet leave no #JVM hs_err crash file.
In catalina.sh debug, it logs the startup, sits idle, then the debugger reports 'disconnected'. This suggests it self-destructs, rather than an external kill - 9?

here's an Apache #Tomcat #Java thing I'd never heard before and although a tech gave it as an excuse, I do wonder if it is true. Apparently, if a Tomcat app receives an HTTPS request and it cannot decrypt the keystore, the entire JVM crashes. I've been using Tomcat since its debut and Java since it was Oak, and I ain't never heard of THIS one before. True?
Tomcat9 on Java8 if that matters.
