This reminds me...  Here I have a Sun 3/80 running 4.1.1 that is waiting
for NetBSD/Sun3x.  Every now and then I see a "zs3:ring buffer overflow".

At work I have a Sun SPARC 1000 with 2 processors running Solaris 2.5 that
every now and then gets a "zs3:ring buffer overflow".

Sun acknowledges the bug and shrugs...
