Hi, Thank you for the information. We will try out the below suggestions.
I have a few more questions, which are facing in the application. The application has *2 solr (v 8.4.1)* and *3 Zookeeper (v3.6.2) *running in SolrCloud mode. After running it for few days we could see below error in logs - 2021-04-12 11:04:26.850 ERROR (qtp1632497828-1072) [c:datacore s:shard1 r:core_node4 x:datacore_shard1_replica_n2] o.a.s.u.SolrCmdDistributor java.io.IOException: *Request processing has stalled for 90083ms with 100 remaining elements in the queue*. and 2021-04-12 09:00:36.350 ERROR (qtp1632497828-786) [c:datacore s:shard1 r:core_node4 x:datacore_shard1_replica_n2] o.a.s.s.HttpSolrCall null:java.io.IOException: *Task queue processing has stalled for 90175 ms with 92 remaining elements to process.* 1. What do these error messages mean? How can we resolve this? 2. After getting these messages, the 2 Solr nodes show different document count and delete count. It seems the 2 Solr nodes are not sync(screenshot attached for reference). 3. One of the nodes (not leader) goes to a recovering state forever. 4.In the solr update requests of 1 Lakh records, there are few thousands of delete query as well. Do the delete query introduce more slowness in synching the nodes The above messages are coming frequently from both the Solr nodes and finally one node goes to a recovering state forever. Could you please help by answering the above queries. Thanks, Rekha
