We are using sunspot solr in our rails application. Large data we reindexed using sidekiq worker in background.

Sometimes we got below issue while reindex data

RSolr::Error::Http – 503 Service Unavailable

Error: {“responseHeader”:{“status”:503,”QTime”:308},”error”:{“msg”:”Error opening new searcher. exceeded limit of maxWarmingSearchers=2, try again later.”,”code”:503}}

using sunspot-rails gem for integration

Any solution?
