Symptoms

Consider the following scenario:
  • You have the hotfix from Microsoft Knowledge Base (KB) article 2590839 installed on a Microsoft SQL Server 2008 R2 or Microsoft SQL Server 2012 instance.
  • You host a database on an instance of SQL Server.
  • The database has a table that is stored as a heap.
  • You enable data compression on the table.
  • You enable Read Committed Snapshot Isolation (RCSI) for the database.
In this scenario, you receive the following latch time-out message on the Page Free Space (PFS) page:

Time Stamp SpidID Time out occurred while waiting for buffer latch -- type 3, bp 0000000500DA4380, page 1:1, stat 0xb, database id: 10, allocation unit id: 6488064, task 0x00000004538BF0C8 : 0, waittime 300 seconds, flags 0x100000001a, owning task 0x00000004538BF0C8. Continuing to wait.

Note To recover from this issue, you might have to restart SQL Server, or you might have to kill the process in Task Manager.

Cause

This issue occurs because an exclusive latch on the PFS page is not released after a ghost bit is updated on the PFS page.
