I have seen this error in 2 circumstances, and only on MVME167 CPUs under
vxWorks 5.4 and EPICS R3.13.3.

1) Right after iocInit.  In that case it seems to be benign, as you suggest.

2) After several hours of intense communication with some non-TCP/IP
Ethernet modules, using etherInputHookAdd. In that case the error is
serious, the IOC cannot communicate on the network at all, although there is
no other indication from the vxWorks console that anything is amiss.  This
problem is an active case with WRS for me now.
The software which is running when we get this failure is basically
unchanged from software which works fine under vxWorks 5.3 and EPICS
R3.13.1.1.
