SQL Articles by Nani
Finished Masters in Computer applications and started the career with SQL application and DBA support. Have experience working with different versions of SQL starting from SQL 2000 to 2014. Also worked on SSRS and SSIS. Currently working in US based company as SQL DBA and Developer. I am very much interested in documenting SQL Server information and doing it everywhere as required. I love learning, working and documenting SQL Server.
Lock request time out period exceeded. (Microsoft SQL Server, Error: 1222) Posted on 2 December 2016 Comments Issue: I see this issue when I try to expand the databases and any other things in object explorer of secondary replica of AlwaysOn SQL instance. I have seen few blogs which suggests to see sp_who2 results and kill blocking. Unfortunately this is read only database and no user connections found. However I have noticed many system sessions running from many days by taking much CPU and IO but I cannot kill them. There is reason for this, this database is out of sync with primary and DPM failing to take log backups from many days.
