5/12, I had a load testing server become unresponsive while monitoring with FusionReactor. A lot of threads were stuck at the following point, and I couldn't force-kill them with FusionReactor.

Just as I was filing this ticket, production failed in a similar way, requiring a Lucee restart. Here is the stack trace dump: https://gist.github.com/jamiejackson/d248cf956929ce0c42ae#file-production-stack-dump-L1021-L1027
