"rpcinfo -p" looks ok on BADSERVER and GOODSERVER.
Also NFS mount is slow on the BADSERVER.
When "rpcinfo -p" finishes on the BADSERVER, it shows the output correctly.
Question: What network (?) issue could this be? AIX 7.
When I am running showmount with truss
_enrecvfrom(20, 0x200263B0, 400, 0, 0x2FF20598, 0x2FF20570, 0x00000000) = 28
It seems it doesn't gets this "enrecvfrom" - compared to the GOODSERVER.
It can resolv the domain name and we tried with only IP too.
UPDATE: DNS server is pingable and resolves domains via "dig foo.bar @DNSSERVERIP"
