We have Hyper-V replica setup between two hosts across a VPN.  VMHOST001 is the primary where all of the machines run, and VMHOST101 is the secondary/DR site where the machines sit just in case.

Today, at 11:22, one of our four machines stopped replicating.  We received the following errors -

Description:
Hyper-V could not replicate changes for virtual machine 'EXCH001': The connection with the server was terminated abnormally (0x00002EFE). (Virtual Machine ID 23C80A90-07BE-4DB3-BC65-DA796692F60A)

All of our other machines on this host are replicating just fine.  We're doing replication using Kerberos as both hosts are on the same domain.  Machines are both Server 2012.

I noticed that the DR host has two temp hrl files - one empty, the other small.  As a test, I moved these to a temp directory and tried replication again.  No dice.  I then restarted the Hyper-V service on both servers and it started replicating and generating the temp hrl files again.  Failed again.

Any ideas?  At a loss on this one.  Nothing on Google, and makes no sense since the machines are communicating fine otherwise.

My initial thought is disk space on the host disk partition for that VM.

80 gigs free.  Only have ~2 gigs to write.

Not for the target (so writing is not yet an issue) but on the source. Hyper-V replica still needs room to make the replica deltas.

Any other partitions close to full when the VM in question is in a running state? System or log partitions could cause similar problems, although it is less common.

About 100 gigs free on the system partition of both hosts.  These are brand new boxes.  The other four VMs are still replicating just fine.

And I guess sometimes, patience is a virtue.  No idea why, but after 5 hours, it just started working all by itself.  Nothing helpful in the logs.
