📝 Describe your problem

After some days of valid execution, the system didn't work and in the directory /opt/uptime-kuma/data I found an error.log file described below. It seems that from this point onward kuma service doesn't run correctly.
Do you have any kind of solution? Thank you very much.

Please see the following issue why this is happening and what we have done to combat this:

• v2.0.0-Release <- Read this for performance problems #4500

Your number of monitors * ping time * retention time is currently too high.

V2 does solve the issue, consider giving 2.0.0-beta.1 a try if the releaseblocker is okay with you: https://github.com/louislam/uptime-kuma/issues?q=is%3Aopen+is%3Aissue+label%3Areleaseblocker
