Hi Yogendra, you mentioned you are using SolrCloud. In SolrCloud an investigation does not isolate to a single Solr log : you see a timeout, i would recommend to check both the nodes involved.
When you say : " heap usage is around 10 GB - 12 GB per node.", do you refer to the effective usage by the Solr JVM or the allocated heap ? Are you monitoring the memory utilisation for your Solr nodes ? Are Garbage Collection cycles behaving correctly ? When a timeout occurs, something bad happened in the communication between the Solr nodes. It could be network, but in your case it may be some Stop World situation caused by GC. ----- --------------- Alessandro Benedetti Search Consultant, R&D Software Engineer, Director Sease Ltd. - www.sease.io -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
