Thanks

Ian Pease And David B Harrington

For that fast answers

I could confirm that it's was a network problem
As it was a other SUN server on the same network lost it's connections as
well but it didn't
Write anything about it in /var/adm/messages

But as we all now the network managers couldn't see anything that's was
wrong and denied it
It was any problem as usual

Cheers Christer

Chris;

I had the same thing a while ago. There are some notes in the archives,
including my problem statements.

I never posted a summary (my BAD!). The issue turned out to be a bad port on
the switch!! (which My network folks denied the possibility of this, but
push them to check it out.

I have found this is a Network Switch issue every time
it happens here.....
