Nfsstat -s many TCP badcalls, no UDP or IPV4 or IPV6 badcalls

Looking at nfsstat -s on a too-busy filer:

Server rpc:

TCP:

calls       badcalls    nullrecv    badlen      xdrcall   

623374644   4294965579  0           0           4294965579

UDP:

calls       badcalls    nullrecv    badlen      xdrcall   

94335674    2           0           0           2         

IPv4:

calls       badcalls    nullrecv    badlen      xdrcall   

717710318   3           0           0           3         

IPv6:

calls       badcalls    nullrecv    badlen      xdrcall   

0           0           0           0           0         

Server nfs:

calls       badcalls

717708871   0      

Why are IPV4 badcalls and IPV6 badcalls near zero? Shouldn't they be more or less the sum of TCP + UCP badcalls?

Even though badcalls=xdrcalls? (which is interesting by itself and might be the result of a bug in Objectivity and its proprietary brain-damaged NFS stack.)

I don't think this is a counter wrap issue (even though TCP calls seems to have wrapped.)

xdrcalls are calls that could not even be decoded by RPC layer. badcalls are calls that have been decoded but rejected.
