A container migration attempt fails with the following errors:
vztar : /bin/vztar: -: Cannot write: Connection reset by peer vztar : /bin/vztar: Error is not recoverable: exiting now /bin/vztar exited with code 2

The container has a large amount of inodes inside.
The allowed SSH inactivity period is insufficient and doesn't allow the migration to complete.
Enable SSH client keep-alive probes on the source server:
