Has anyone encountered this? We are using SQL Server 2012 Enterprise Edition with SP1. During a time of low/no activity, I noticed the Ghost Cleanup process is utilizing CPU at a very high rate, from 75% to 99%, these aren't bursts but sustained usage.
Is this a bug with SQL 2012? I have seen this in SQL 2008 R2 and there was a fix for it but I haven't seen anything for 2012.
