Arithmetic overflow error converting expression to data type bigint UI bug?

[cerberus]

We are using latest VBR10 (10.0.14854). Recently started using Veeam replication jobs to push VMs from PROD to DR.

After a few successful runs, clicking on the replication jobs throws UI error "Arithmetic overflow error converting expression to data type bigint".

Everything seems to work fine, jobs run without issues.

Using the included Microsoft SQL Server 2016 (SP1-GDR) (KB4505219) - 13.0.4259.0 (X64) Express, locally installed on the same server as Veeam.

The environment is fairly small (3 hypervisor, 40VMs, B2D2T, replication). Veeam sits on a dedicated beefy backup server hardware.

Being told we are over utilizing the SQL Express instance and to SQL install?! I find this hard to believe as the error happens even with just one replication job running after a fresh reboot of the server.

Seems like a UI bug where Veeam is trying to store a value that overflows the field data type?

Please keep working with support - it might be a known one, I have passed a word to support engineer handling your case.
Just wondering, are you using WAN Accelerators with your replication jobs?

/Thanks!

Hi Egor,

Yes we recently started using Veeam WAN accelerators (many to one deployment) to help with the daily sync. We also had to seed a few large VMs (backup copy job to USB stick) and IIRC this is when the error started showing up.

Thanks Egor,

The fix provided by support resolved our issue, no more errors.
