| **Bug 343-Workaround** vzmigrate error upon failback - /dev/stdout: No such device or address [message #8129] |

I have two hosts on the same local network, same version of OpenVZ (2.6.9-023stab032.1-smp), the main host (HARPALYKE) is running 20+ VMs without a problem. The other system (OTHOSIE) can create VMs and run them as expected.
I can vzmigrate a VM from the main to the secondary and after the ARP tables on the switch update it works perfectly but when I try to fail back I get this error:
[/]# vzmigrate -r no -v harpalyke 121
OPT:-r
OPT:-v
OPT:harpalyke
Starting migration of VE 121 on harpalyke
bash: /dev/stdout: No such device or address
OpenVZ is not running on the target machine
Can't continue migration
I don't know where to go from here. Please help me understand why on two identical machines I can fail one way but cannot fail back ..

both systems have VZ running, esp from the secondary to the primvary since it hosting 19 ofther VMs
The VM version on the main (was):
[harpalyke ~]$ rpm -qa |grep vzctl
vzctl-lib-3.0.10-1
vzctl-3.0.10-1
but since has been updated to match the secondary, which is:
[othosie ~]# rpm -qa |grep vzctl
vzctl-lib-3.0.12-1
vzctl-3.0.12-1
Distribution os both systems is CentOS4 for the host and VMs

I tested two VMs, one was created on OTHOSIE and cannot migrate to HARPALYKE (VM:121) and the other came from HARPALYKE to OTHOSIE correctly but cannot return (VM:103).
