SQL 2008 R2 SP2 event id 18056

Hi,
Trying to troubleshoot errors I have found just recently in my app log on my SQL 2008 R2 SP2 server.  See the error below.  I have read lots of posts online concerning this error but I haven't found any resolution.  Can anyone shed some light on this issue?  When I first found this error yesterday I was on SP1 and I have since upgraded to SP2, however the errors still occur.  My server resources are running normal when these events occur.  When these events are occurring  some users are reporting very slow login times for our SQL app and very slow while working in the app.  Thanks for your help.

Hi,

You're experiencing kind of generic type of this error, please try to find some info in sys.dm_os_ring_buffers DMV (use following link for queries).
