dropped udp packets - due to no socket

dropped udp packets - due to no socket

Post by John Martinet » Tue, 19 Oct 1999 04:00:00



Hi Folks:
I am having a problem with poor network performance.
netstat -p udp indicates a large percentage of dropped udp packets due to no socket.  I'm new to AIX and networking in general so any help would be appreciated.When these "spells" occur I experience some real sluggish network performance.
Thanks

dropped udp packets - due to no socket

What are you running?  any uucp or nfs going?

look at the udp_sendspace and upd_recvspace  and sb_max using no -a.  these, if
determined they should be changed, can be changed using the no command.
However, more about what is running will help determine what is the cause.

Good Luck :-)

These will have nothing to do with "dropped due to no socket."

1. UDP Datagram dropped due to no socket.. . why?

Hey guys:
I've noticed on several machine that doing a "netstat -sp udp" shows and
inordinate number of broadcast/multicast datagrams dropped due to no
sockets.

Q:Is this normal?
(some of these systems are relatively inactive. ie no NFS or non system
daemons running, not even users logging in.)

I think that this is as a result of normal systems activity  but I'm
just not sure about it.

Thanks
