SUMMARY
Persistent Storage Manager (PSM) Service Pack 2 (SP2) is the most recent version of PSM version 2.2 that is available to vendors of Columbia Data Products.

This package provides improved reliability for users of existing PSM version 2.2 who currently use Service Pack 1 (SP1). Some of the fixes that are included with this service pack have been previously released as separate hotfixes. This service pack combines the updates in one integrated package. This service pack includes other changes that are designed to improve the reliability of PSM.



Bug Fixes That Are Included in PSM SP2
Persistent Storage Manager SP2 includes fixes for the following issues:
 * You might receive a 0x07F stop error on a blue screen because of filter stack overflow.
 * The &quot;\snapshots&quot; directory is needlessly created.
 * You receive an occasional stop error during a cluster rapid rolling fail-over.
 * You may receive a stop error when you rename a snapshot junction point.
 * Memory leaks when a user requests PSM volume information.
 * The computer may stop responding during startup if the PSM cache usage is between 80% and 90%.
 * The computer may stop responding if the NTFS file system volume is not formatted correctly or if the NTFS data structure is bad.
 * You receive a stop error when you run the Reextended.exe program for a basic type volume.
 * You receive stop errors if the system has extremely low virtual memory.
 * The Open Transaction Manager driver (OTMBridge driver) is not compatible with third-party backup software.
