Subject Re: Both main and replica are trying to access solr_gc.log.0.current file
Date Sun, 30 Apr 2017 05:52:24 GMT
It might depend some on how you are starting Solr (I am less familiar with
Windows) but you will need to give each instead a separate log4j.properties
file and configure the log location in there.

Also check out the Solr Ref Guide section on Configuring Logging,
subsection Permanent Logging Settings.
