Ignition v8.1 perspective project CPU overload issue

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).
