My website is using 70% to 100% of CPU, but i don't have any modifications, it's ocurred a 3 days ago.

In one day later it's is 0,5 to 10%,
but now is in the most time it's 70% to 100%.
I sleep in one day later and in the next day when i use my computer i observed it.

Sometimes it's 14%, but in more time it's grather then 70%, it's a teste server,
I'm the only one who connects there

Please copy/paste the above report in your issue on https://github.com/Unitech/pm2/issues

Start with the supplied PM2 report and daemon logs, especially the cluster-process disconnects, exits, and restarts. Reproduce or isolate the sustained CPU usage using the reported PM2 4.5.0, Node.js 10.7.0, Linux, and one-CPU environment; done means the cause is identified and the behavior can be verified.
