Recently I met a strange issue on Ignition V8.1 perspective project，the CPU usage is extremely high and achieve 98%，current is 4 cores and 16GB memory, I also put screenshot in there(10 sessions at this time)

May I ask did ignition team also met similar issue before and have any experience can share with me like hardware( multiple servers, cores, memory etc.), program principle, configurations or something I should try to avoid to use，etc.

Get a thread dump while the CPU usage is high and share it here.

I've seen this many times, and it almost always is a programmer error (infinite loop of some kind).
