TdsInputBufferError not 0 in LoginTimers errors of RING_BUFFER_CONNECTIVITY of sys.dm_os_ring_buffers

I've got an issue with SQL Server.

The value of TdsInputBufferError is not 0 in LoginTimers errors of RING_BUFFER_CONNECTIVITY of sys.dm_os_ring_buffers.

This happens randomly, once or twice a week, at different times.

Is it an issue with networking drivers ? Virtualization infrastructure? What to monitor to find out? There is no other error/warning log anywhere (windows logs, syslogs, ...).

I can't give you answer but I can direct you towards it.

• You need to download the public symbols for your installed

version of SQL Server
http://www.sqlskills.com/BLOGS/PAUL/post/How-to-download-a-sqlservrpdb-symbol-file.aspx

• You need to able the Trace Flag which shows the public function names for

that Stack Trace using DBCC TRACEON(3656) with reference to this blog

• Report the public symbol names for those frames back to us or
