The EM log is repeating showing the warning message pattern that follows. These messages have increased the size of the log files and it is unclear of the impact to the APM cluster.

3/06/18 05:08:10.375 PM GMT [WARN] [Raw Data Stash] [Manager.AppMap.UVB-Mapping] Processing of UVB metrics is overloaded, ignoring the new one! 3/06/18 05:08:25.062 PM GMT [WARN] [master clock] [Manager.AppMap.Alert-Mapping] Processing of alerts is overloaded, ignoring 500 new alerts!

How can I eliminate these errors?
APM 10.5.1
Upgrade to APM 10.7 from 10.5.1 may help.
