MySQL 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.

NAME
ipc - System V IPC system calls SYNOPSIS
int ipc(unsigned int call, int first, int second, int third, void *ptr, long fifth); DESCRIPTION
ipc() is a common kernel entry point for the System V IPC calls for messages, semaphores, and shared memory. call determines which IPC function to invoke; the other arguments are passed through to the appropriate call. User programs should call the appropriate functions by their usual names. Only standard library implementors and kernel hackers need to know about ipc(). CONFORMING TO
ipc() is Linux-specific, and should not be used in programs intended to be portable. NOTES
On some architectures--for example x86-46 and ARM--there is no ipc() system call; instead msgctl(2), semctl(2), shmctl(2), and so on really are implemented as separate system calls. SEE ALSO
msgctl(2), msgget(2), msgrcv(2), msgsnd(2), semctl(2), semget(2), semop(2), semtimedop(2), shmat(2), shmctl(2), shmdt(2), shmget(2) COLOPHON
