Veeam services crash after installing KB3216755, KB4010672

Hello,

Case 02059399

we migrated all our backups back from REFS to NTFS but still installed the MS hotfix KB 3216755.

Now our Veeam services crash after ~12 hours with System.OutOfMemoryException.

There were no actions done on the REFS since the last Reboot and the Server has 128 GB of RAM. But there was at least one Veeam.Backup.Service.exe which used 32 GB RAM...

More info: at the time of the last crash there were only a few copy jobs and one big tape job running...

It happened 2 times in 24 hours.

After talking to Veeam support we uninstalled the MS update. System behaves normal again but REFS will be much more unstable.

Gladly our move back to NTFS was already finished...

As I have already warned in the corresponding thread, per Microsoft the current KB3216755 package seems to be in the "pre-release preview" state, so I would not recommending deploying it in production environments until it is officially released through Windows Update.

@Gostev thank you - i just wonder why we are the only ones with this issue. I just uploaded a 40 GB process dump of the veeam backup manager process.
Maybe your team finds something as well :-)

Whats really interesting is that the Veeam Services which took the 40 GB now after the removal of the update and several backups only takes 94 MB

Just a small "me too" about veeam.backup.manager processes taking over 60 GB of ram since applying KB2316755.

Same issue for us too, after installing kb3216755 the Veeam services/server run out of memory.

We get several Resource-Exhaustion-Detector events:
Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: Veeam.Backup.Service.exe (8916) consumed 107299299328 bytes, Veeam.Backup.EnterpriseService.exe (9236) consumed 2399756288 bytes, and Veeam.Backup.Manager.exe (6908) consumed 1611759616 bytes.

We have a case open with Veeam and the memory dumps are being analysed.

Without kb3216755 we get deduplication data corruption.

I don't know why Veeam think KB3216755 is pre-release, the MS article https://support.microsoft.com/en-gb/hel ... -kb3216755 doesn't mention pre-release or preview. Can someone clarify?

Thanks

The info "This release is only available on the Microsoft Update Catalog website" is kind of a hint. Also it is not generally avaiable in microsoft update....

OK, so the crash dumps were not immediately helpful because the leak is happening outside of the managed code. For now, it does not look like the issue is in our code - but it is really hard to diagnose since leaking is unmanaged memory. However, the leaked memory content seem to contain lots of SQL Server stuff (column names, stored procedure parameters and such), which prompts to ask all of you the following question - do you use local or remote SQL Server?

I know most of you in this thread are affected by the issue, but I also saw one confirmation on the other thread that someone else did not have any problems after installing the update. So, if we can confirm that all of you affected have local SQL Server installed on your backup server, and those who are not have remote SQL Server - this will be a big step forward in the investigation.

Thanks!
