Here is some numbers I'm seeing from an nfsstat -d on one of my filers:

num msg=0, too many mbufs=3631, rpcErr=3532, svrErr=0

I can see from the man page that the too many mbufs error means that there are udp packets being dropped because there are not enough mbufs available. What I can't find out is what if anything I can or should do about it. I've searched around on now but haven't found a specific mention of this for some reason (possibly just because I haven't had my coffee yet).

Anyone have any advice one whether those numbers should be a cause for concern?
