Hello Shawan, Thanks for your suggestions.
We are using Java 8 Update 261 (8u261). Does upgrade of JAVA version will be helpful? We have provided GC analysis images of issue time only. However, GC logs of longer duration. Regards, Jay Harkhani. ________________________________ From: jay harkhani <jay.harkh...@hotmail.com> Sent: Wednesday, September 8, 2021 6:02 PM To: users@solr.apache.org <users@solr.apache.org> Subject: Replica went into Recovery mode in Solr (v-6.1.0) Hello, Greetings for the day!
