A few days ago some users reported problems connecting, they were freezing.
A ping from the affected pc's showed "Source quench received" returned. This was NOT returned from PC's that were not affected when run at the same time.
All the connections were going to the same IP address, and same network card, just some of them had issues.
Any advice on what might be the cause, can't find any errors on the hpux box, and suspect it might be network related.
Solved! Go to Solution.

Re: Source quench received from ping
You can get rid of this messsage by doing:
# ndd -get /dev/ip ip_send_source_quench
If it returns 1 then try setting it to 0
# ndd -set /dev/ip ip_send_source_quench 0
But you need to find out why this is happening. Have a look at this link below.

Hope that helps.

Re: Source quench received from ping
I had this same issue start occurring several months ago on one of my systems. And through all the t-shooting, I never found the culprit.... Through various research, it was suggested that the ping response was being received faster than the HP-UX system could handle it. Has something (network-related) changed recently?

SolutionA source quench received message usually comes from a router in the path the ping was headed.
They do this when they start to become saturated with traffic. They deal with the saturation by starting to discard "low-priority" traffic of which ICMP traffic is one of the first. Ping uses ICMP traffic.

Re: Source quench received from ping
I agree and think that this is a network related issue, but our network guys dont agree.
Well I have disables the Source quench messages from the server, and in the event of a recurrance of these problems I have asked our network guys to check for these messages to identify the problem as not being server related.
Thanks again, and Jeff u get 10 points as I used the text of your reply in my email update on the issue.
Thanks again everyone.
