Ang: Re: netmon and /etc/hosts ?
Try putting this in the /etc/netsvc.conf file:
We had DNS lookup problems when we changed our DNS servers from AIX to NT.
The problem was that all our AIX 4.3.2 servers took very long time to resolv
We got help from AIX support and they told us to use "bind4" in
it has to do with the IPv6 implementation in bos.rte.libc.188.8.131.52 .
By default all name resolution is done looking for IPv6 addresses first, then
this could be a problem with some DNS servers.
Maybe this is the case here??

This is just too interesting. You are probably right about fgets and
How do you get this stack trace, and how do you know it's hung in those
routines? When I run dbx, it stops the program and then I can look at the
trace, so all I get are snapshots. Is this one such snapshot?
TKG has a nice tool called sctrace. You could get a trial version that will
show you the last 30 system calls. It shows more details than dbx does, and it
can show you the timings and arguments as well. 30 lines ain't much but it may
be all you need in this case.
I think it is interesting that it works fine after you clear the snmpconf
Note that the stack trace gets to the ho_get* calles from
I seem to recall that there were some issues with IPv6 and AIX 4.3 (maybe
4.3.2) that talk about using bind3 or some such.
I think you need some really good tracing tools for this problem. Maybe not
clearing the cache will cause a bunch of host lookups to occur and that's what
is screwing you up.
