Ignition 8.1.42 We have an issue with the performance. The CPU goes very high 4 to 5 times per day and we need to restart, I'd like to be able to do a memory dump and send it to the IA support for analysis. In order to do that I need to install the JDK. Which JDK should I install and where do I fin dit? Thanks,. ---

You should ask support to guide you. Answers are platform dependent and java version dependent. ---
