BMC Error - Malformed message received.

[J Rangi]

We just bought some Dell PE 19XX servers, I configured the BMC on those. 
BMC was working fine for first few hours and then I started getting this 
error. Can some help me how can I get rid of this. I get the same error 
when I try to connect using solproxy.
