[ID #03954027] Transmission pipeline hanged

Post by KamSandhu44 » Jan 15, 2020 8:54 am

Hi all,

I am having issue's backing up two of my HyperV hosted VMs. I have the latest version of Veeam Backup & Replication (the community edition).

Two Vms are failing with Transmission pipeline hanged, aborting process. (Veeam.Backup.Common.CCppComponentException).

Snipet of the log: -

I am logging to a local NAS, my other seven VMs backup fine.

Any guidance would be great.

Hello!

Generally, this message means that data transmission between Data Mover components is stopped by some reason but connection still exists.

According to log snippet, there is an issue with writing data to a NAS which seems to be overloaded:
- May be you run too many tasks in parallel to the NAS and it would make sense to reschedule backup of 2 problematic VMs
and backup these VMs in a separate job or to decrease concurrent tasks number at the level of repository settings
- There is a hardware issue with NAS itself which affects data write process

Anyway, let's wait for results of troubleshooting from our support team.

Thanks!
