One other piece of information. There are 2 applications using BaseX on this system. They are using 7.6, while I am using 7.9. I  am using alternate ports for the server and events.

Difficult to tell. Do you always close server instances? – Any reproducible use case would be appreciated.

I have a highly multithreaded application that uses BaseX as a translation/transformation engine. It has been functioning in production for almost a year. From time to time I see the following in the nightly report the application generates which is sent from the server hosting the application. It requires a restart of JBoss, used as the application server. Any ideas?
