If there are three different Apache Tomcat instances running three different services on Java 11, the only explanation to make one crash that comes to my mind is the resources of the machine, memory in particular. The recommendation is to not use more than 75% of the memory of the host to the JVM, in your case you have 3 JVM running so each should not use more than 25% of the memory of the host, if you use more than that the JVM will fight for the host resources and one will lose crashing. Check the values on your `xms` and `xmx` Apache Tomcat parameters.
