Dell ActiveArchive, v.v2.2 b2283, A04

1. Fixed: Hang when out of virtual memory
If the system's virtual memory that is needed gets low, (or runs out), it may lead
to a hang. This hang may eventually lead to a bugcheck with an 0x0000004D error.
The reason is PSM was trying to use virtual memory when PSM was supposed to make
it available.

2. Fixed: Computer that is running Microsoft Windows Powered Network-Attached Storage 2.01 may stop responding, and the CPU usage may increase to 100 percent. Additionally, you may receive a Stop error message that is similar to the following:
Stop 0x0000004d
NO_PAGES_AVAILABLE

3. Fixed: Low stack was using worker threads as was NFS, which would compete for the same resources, causing a system hang when doing NFS client traffic. Now PSM have his own thread which queue the requests to.

4. Fixed for NFS Virtual Server hang during heavy io.

5. Fixed slowness issue in cluster environment: When snapshots created, then all deleted, then volumes failed over to other node, "My Computer" displayed volumes extremely slowly. Now there is no perceptible delay.

6. Fixed: Thread object leak when running on cluster. This would cause the OS to eventually eat all nonpaged memory for tag 'Thre'. This occurred when during failovers back and forth

7. Fixed: Handle writes that occur at dispatch level. This solves an interoperability issue with Veritas Backup Exec 9.x with their AOFO option (vsp.sys)

8. Fixed problems in OpenCacheFiles that happened when multivolume snapshot failed.

9. Fixed hangs that can happen if exception occurs in pd::searchAndInsertMultiple.

10. Fixed: No longer prevent snapshot creation just because cache usage is high.

11. Fixed low stack conditions.

12. Fixed accessing physical volume during mount. This solves an issue with NAV 8.0 when it scans for boot sectors.

13. Fixed: Leaking file system filter device object that was created during mount when mount fails for some reason.
