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, ...).

Full ringbuffer report:

This question came from our site for system and network administrators.

Winsock Error 10054 is "Connection reset by peer", or "An existing connection was forcibly closed by the remote host". – Martin Smith Jan 21 '12 at 10:12
ok so it means something is wrong with the network somewhere. – Softlion Jan 23 '12 at 8:17
Not necessarily. Maybe you can reproduce this error by killing a client mid query. Not sure, haven't tested. – Martin Smith Jan 23 '12 at 9:34

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
  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).
