The information in this article applies to:

  - Microsoft SQL Server version 4.2 for OS/2

SUMMARY

This article describes the following error message that may appear in the SQL Server error log:

   nnextread: count changed from XXX to YYY.

MORE INFORMATION

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.
