Errors in Solr log

[Hemant Verma <he...@gmail.com>]

We are using Solr 6.6.3 with Sitecore. Solr is installed on windows.
Below are few errors coming repeatedly in logs. What could be the possible
fix and reason for below errors.
FYI, we are not interested in using configoverlay.json, this could be one
reason of error and this file exist by default. Can we remove/delete
configoverlay.json?
