VBR 9.5u1 / Win2016 high memory usage (Case # 02067403)

[antipolis]

Greetings,

Last week I reinstalled our VBR server under Windows Server 2016 and migrated our repositories to ReFS, to take advantage of fastclone.

What I did :

- Configuration Backup
- Fresh install of Server 2016
- Fresh Install of SQL Server 2016 Express
- Fresh install of VBR 9.5 + update 1
- Configuration import from backup

I noticed that since the upgrade VBR is eating all my memory :



Our server has 64 GB of RAM which should be more than enough (it was before migrating to Win 2016).

If I restart the server then RAM usage seems reasonable for some time but slowly fills back all the available memory in 24-48 hours.

Jobs are now randomly failing with some pretty straightforward errors, for example :

Processing XXXX Error: Shared memory connection was closed. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.
Error: bad allocation Unable to retrieve next block transmission command. Number of already processed blocks: [188]. Failed to download disk. Shared memory connection was closed.
Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.

Error: Une exception de type 'System.OutOfMemoryException' a été levée. Error: SQL server is not available


I could not find any relevant information in the KB or the forums, so some help would be really appreciated.

Regards

Did you install KB3216755 or KB4010672? Looks exactly like our "old" problem with these updates:

Thanks for your feedback

KB4010672 is installed, KB3216755 is not

I did not install any hotfix manually, only used windows update

also worth to mention I formatted ReFS with 64k cluster size

KB4010672 is installed, KB3216755 is not

I did not install any hotfix manually, only used windows update

ok after double checking I got this wrong, in fact I DID install KB4010672 manually... after fresh install OS was not updating correctly via windows update, so I installed this update cause it seemed to me a good idea to install what seemed to be the latest cumulative update

I will try to uninstall this... once again thanks for your feedback
