Can you tell me some info about your AIX box?


model/cpu's/memory

oslevel -r

lslpp -l bos.net.*

no -a
ioo -a
vmo -a

do you run NFS and/or dhcpsd on this box? other network services?

have you had to reboot ther server or restart samba to get the problem to go
away?

does errpt show "SYSVMM out of network resources" ?

And I agree with Jeremy; software doesn't just stop working without a darn
good reason...and it's usually the OS if you've truly changed nothing. Can
you give load and timeframe information? Do you use local user (/etc/passwd)
files or LDAP? We need LOTS of info for an issue like this....

Cheers,


Bill
