errors on Netra-440: "IPC Warning: ipc: tcp_protocol: bad magic number"

I was asked to look into a problem with a Sun Netra 440 in another department. On the server in question, the relevant 'uname -a' information is, "SunOS host1 5.9 Generic_118558-16 sun4u sparc SUNW,Netra-440". That information aside, while the other admin is logged into the ALOM, these errors are scrolling steadily across the console:

IPC Warning: ipc: tcp_protocol: bad magic number
IPC Warning: ipc: tcp_protocol: bad magic number
IPC Warning: ipc: tcp_protocol: bad magic number
IPC Warning: ipc: tcp_protocol: bad magic number
IPC Warning: ipc: tcp_protocol: bad magic number
IPC Warning: ipc: tcp_protocol: bad magic number

I have not seen "bad magic number" messages associated with "ipc: tcp_protocol" before. Has anyone encountered and/or fixed such errors before or can anyone direct me to documentation describing IPC Warning messages on the ALOM level?

Thanks in advance for any assistance with this.
