Hammer & Screwdriver Interface goes into promiscuous mode

Hi all,

I am using a Linux VM.

Once the node boots up, I am able to access it and it is able to ping its default gateway.

At that time, the config is;


Code:
eth1      Link encap:Ethernet  HWaddr 00:50:56:01:01:FB  
          inet addr:142.133.174.246  Bcast:142.133.175.255  Mask:255.255.254.0
          inet6 addr: fe80::250:56ff:fe01:1fb/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1857 errors:0 dropped:0 overruns:0 frame:0
          TX packets:234 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:211236 (206.2 KiB)  TX bytes:22344 (21.8 KiB)

But within 2 minutes, I cannot ping from or to this VM any more and cannot even ping the gateway.

The config then is;

Code:
eth1      Link encap:Ethernet  HWaddr 00:50:56:01:01:FB  
          inet addr:142.133.174.246  Bcast:142.133.175.255  Mask:255.255.254.0
          inet6 addr: fe80::250:56ff:fe01:1fb/64 Scope:Link
          UP BROADCAST RUNNING PROMISC ALLMULTI MULTICAST  MTU:1500  Metric:1
          RX packets:1857 errors:0 dropped:0 overruns:0 frame:0
          TX packets:234 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:211236 (206.2 KiB)  TX bytes:22344 (21.8 KiB)

Why does the config change and how can I stop it ?

What other checks should I go through ?
