Memory Leak Issues Being Reported With KB2799728

I mentioned a new KB article/hotfix yesterday that resolves an issue with backup of CSV on WS2012 Hyper-V clustered nodes.

Tim Boothby and Rich Lilly commented on the post that people are reporting memory leak issues after installing this hotfix.  My advice: don’t install the update unless:

  • You really need it OR
  • It appears that the issue is resolved

  1. Hi Aidan,

    i have exaktly this Problem on my both Hyper-V Clusters. I Backup my Cluster with DPM 2012 SP1 and all Updates. After i have read this Blog Entry I have updated all Hosts (and resarted) on both Clusters an Backup my VMs again. Now I have exectly this Prblem again. The Microsoft Fix has nothing changed!

    Do you have any idea what i can do th solve this Memory Leak Problem with DPM2012 SP1?

  2. Hi,

    Microsoft released a v2 of this hotfix in KB2813630 which addresses the memory leak issue.

    There do still seem to be issues around CSVs becoming unavailable when running host level backups, people are reporting STATUS_CLUSTER_CSV_AUTO_PAUSE_ERROR(c0130021). Apparently Microsoft are aware and are working on a v3 of this patch.

    This thread on Technet seems to be the best place to keep in touch with this issue –


  3. We have found that the issue only occurs if you have FEP installed on the hosts. If you uninstall FEP then the problem goes away. Another work around is to exclude dpmra.exe if you are using DPM. For other backup products you should contact the vendor for the specific exclusions.
