SQL Server Activity Monitor - Resource Waits - Logging > 1400 ms/sec, how? I have an SQL Server 2008 R2 server. I open "Activity Monitor", and inside the "Resource Waits" category, I see that the "Logging" category is taking up more than 1400 ms/sec.

That doesn't seem to be normal, what does that mean and how do I diagnose the cause?

UPDATE:

I ran this query, suggested by Shark: 

select * from sys.dm_os_wait_stats order by wait_time_ms desc


and got these results:

wait_type                         waiting_tasks_count  wait_time_ms         max_wait_time_ms     signal_wait_time_ms

I would check disk health / performance for volumes holding your transaction logs. You are seeing a delay due to the durability requirement, logging is backed up.

Check for I/O delays on tlog files in activity monitor as well.
