Hi All, We are facing timeouts while connecting with zookeeper for indexing.
*Exception Details:* org.apache.solr.common.SolrException: java.util.concurrent.TimeoutException: Could not connect to ZooKeeper 10.128.193.20:2181,10.128.193.21:2181,10.128.193.22:2181 within 15000 ms On checking this further, we found that the total number of connections on the zookeeper cluster was greater than 60. Upon backtracking further, we found that we recently added a new collection on zookeeper [cluster of 3], and the new collection contains 59 shards on which indexing is happening. On stopping indexing on the new collection, everything was fine, and indexing got fine on the other collections, as the number of connections on zookeeper reduced to less than 60. My solr cluster consists of 16 nodes, with 5 collections and >70 shards. Any help on how to resolve this issue and perform indexing on all the collections. Is simply increasing the number of maxClientCnxns [in zookeeper config] the standard way, and if in future I add even more collections, then to what extent should we increase this limit?
