Sorry my English is a bit poor and I don't know if this is the right thing to do. After clearing the cache and restart instance then I connected to the beginning of the project again and let it run still, thus eliminating the need to close and open the project.
After doing this, the CPU has been running for 2 days now and has only been taking up about 5%. Without doing this, it would have been taking up 60% of the CPU after half an hour.
I also do not know if the operation of clear cache and restart instance has any effect,but after doing this, everything works fine.
