Monitoring script fails only on Proxmox.

[KuJoe]

I know this is probably beyond the scope of the support here, but I've run out of ideas and hope somebody here might have one...

So I am using a monitoring script (https://github.com/DimeCadmium/scrd) on 12 servers but 4 of them continue to fail. The only thing the 4 servers have in common is they are on the same hardware which is running Proxmox. Here is a breakdown of the servers:

1 is running Debian 5.0.8 64bit (Proxmox 1.9)
1 of the servers is running Debian 5.0.8 32bit (OpenVZ)
1 is running CentOS 6.0 64bit (KVM)
1 is running Debian 6.0 32bit (OpenVZ)

Here's the actual error I'm receiving on all 4 servers:

Traceback (most recent call last):
File "./scrd", line 221, in <module>
put(ns, simplejson.dumps(dic))
File "./scrd", line 97, in put
if nl: sock.send("\r\n")
socket.error: [Errno 32] Broken pipe

Any ideas why this script works on all of my servers except for the ones utilizing Proxmox? I'm assuming it's a networking issue somewhere but I can't figure out how, why, or where. Again, any help is appreciated.
