In SharePoint 2013 Production, I am trying to do full crawl. However, crawling is too slow and crawl only few items in 1 hour. Log gives below error:-
CManagedSqlSession::InitBulkInsert m_ManagedSqlSession->InitBulkInsert fails with Error 0x80131509 Description 'Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.' Message 'Unknown error 0x80131509'
I have restarted SharePoint search services application, restarted SharePoint server search 15 service, checked web application's pool a/c having access on content DB. Is there anything I am missing in configuration?
I have server:- WFE-2, Application server-3, DB-1 (SQL server 2012/R2), Project server-1
