> [...] so the second Tomcat now shuts down APR globally, releasing the global structures. The first Tomcat is now shutting down, its `AprConnector` tries to use a sub APR pool/object from a pool which has already been released. There is no `AprConnector`. Where is the Java call which eventually goes down into native to cause this problem? As the AprLifecycleListener is stopping, it should not try to use any APR pool. Perhaps the other connector is still trying to actually use pool objects in some other way. If that's the case, the problem isn't with double-shutdown. It's with shutdown-while-trying-to-still-do-stuff. > See > * https://github.com/apache/tomcat-native/blob/c17d3e0e0a594604ff4f30065360aacc688cfb50/native/src/jnilib.c#L243-L262 Notably, even this native method prevents crashes due to double-shutdown. The predicate around the whole thing prevents it from being called twice. So can we get a Java stack trace for where this is crashing? It should be simple to check to see if APR has been killed at some point and at least not crash the JVM. -- This is an automated message from the Apache Git Service.
