Hi,
We have Solaris 10 x86 servers which are used as ClearCase servers.
After a few hours of use we see udpInOverflows when we run netstat -s -P ip
I have modified udp_xmit_hiwa tudp_recv_hiwat and udp_max_buf :-
ndd -set /dev/udp udp_xmit_hiwat 131070
ndd -set /dev/udp udp_recv_hiwat 131070
ndd -set /dev/udp udp_max_buf 8388608
But still we get -
# date;netstat -s -P ip|grep udpInOverflows
Thursday, 10 July 2014 21:20:52 BST
         udpInCksumErrs      =     0     udpInOverflows      =3465587

How can I track what is causing this and how can I see what the values 
could be set to remove the problem
