Experienced the same but with 188.8.131.525.
19 objects in the job. Error message varied on each guest server (object) with one of the four listed:
- Agent failed to process method DataTransfer.SyncDisk
Agent failed to process method DataTransfer.BackupText
Error: Transmission pipeline hanged
Aborting process and Getting VM info from vSphere Error: Socket has been forcibly closed. Failed to recover connection.
- EMC DataDomain DD620
VMware ESXi/vCenter 5.5
Backing up to NFS target (NFS to an intermediate Linux server which has DD620 NFS mounted).
Read through the various solutions, I thought I'd try the easy one first. Changed the TCP Checksum Offload (IPv4) on my Veeam server and on Windows proxy and problem appears resolved.
Being a non-profit, We is too poe to baa production support, so it'll be days and days before support gets back to me. One time it was a week for a backup that was continually failing. Great stuff.
