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

Posted on

Question :

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, …).

Answer :

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

  1. 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
  2. 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
  3. Report the public symbol names for those frames back to us or
    Microsoft CSS (Customer Support Services)

The following .net framework update partially resolved the issue.
See issue 14:

@MartinC I’ll try your tips asap.
(I still have the problem when database backups are running during the night).
