Writes to Databases May Cause Corruption When the Filesystem is Full (Out of Available Disk Space)

(Doc ID 397048.1)

Last updated on OCTOBER 09, 2017

Applies to:

Berkeley DB - Version 3.0.55 and later
Information in this document applies to any platform.

Symptoms

When the disk becomes full, and there is no more available disk space to complete write operations (transaction commits, checkpoints, trickles, database syncs etc), error 28 (ENOSPC) is returned, "No space left on device".

Further writes in the log files or database files aren't possible. The databases may become corrupted unless the application is transaction protected.

Changes

The problem is not generated by any changes in the implementation of the Berkeley DB APIs.
