Summary:
This article describes the following error message that may appear in
the SQL Server error log:
nnextread: count changed from XXX to YYY.
The error NNEXTREAD is an informational message from SQL Server. This
message occurs when the named-pipe packet that SQL Server received was
corrupt and the kernel corrected a pointer. XXX represents the length
of the packet received, and YYY represents the length SQL Server was
expecting. The normal packet for SQL Server is 512 bytes: 8 bytes of
header information and 504 bytes of data. SQL Server will try to
correct the bad packet by truncating the data packet to 504 bytes.
This message is the result of a spurious network problem and should
be of concern only if it happens frequently.
