On-Demand Hotfix for Parallel Batch-Mode Deadlocks in SQL Server 2014

Today Microsoft released a critical, on-demand hotfix for customers using Columnstore indexes in SQL Server 2014. The hotfix addresses a scenario where a batch-mode scan that has gone parallel can deadlock, and the deadlock cannot be resolved automatically.

The hotfix can be downloaded from KB #3048751 and will bump SQL Server to 12.0.2488.

For more broad advice about hotfixes and cumulative updates for SQL Server 2014, see this blog post.
