Database Integrity Check Jobs running for ever in Sql 2012

We have Database Integrity Check jobs running every early morning during off hours into sql server 2012 specially for Share point databases.It's running currently for last 3 days as normally it's finishes in minutes.We are using Ola scripts for our Database Maintenance Solution.I didn't see any errors in logs and also nothing like DB corruption issue.Could you please guide how to troubleshoot to check what's going on?


Check for a blocking process
