Good morning, I would greatly appreciate your help as I am quite lost. For approximately 4 to 5 years, I have had an ERP software running on GlassFish on an AWS EC2 instance. A little over a month ago, it started failing, with one CPU core remaining at 100%. When performing a thread dump, I attach the log of what I find. Beyond the failure itself, why could this have occurred after 4 years without any updates or software changes?.
