Hi,
We are facing a strange issue in our solr system. Most of the days it keeps
running fine but once or twice in a month, we face OutofMemory on solr
servers.
We are using Leader-Follower architecture, one Leader and 4 followers.
Strangely we get OutofMemory error on all follower servers.
Before the OutOfMemory this exception is found on all servers.
