BUG: Disproportional Data File Filling

ID: Q235502

The information in this article applies to:
BUG #: 55726 (SQLBUG_70)

SYMPTOMS

SQL Server uses a proportional fill technique to distribute new data across multiple database files. Under certain space consumption situations, the calculation of free space available in a given file is erroneous and may lead to the situation where more proportionally full data files continue to receive new data, while less full data files do not grow at all.


RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next SQL Server Service Pack that contains this fix.

WORKAROUND

If sufficient disk space is available, increasing each of the smaller files by at least 4 GB has been shown to benefit the situation.
