[omniORB] Source of getaddrinfo delay

Hi
I am attempting to locate the source of the name
resolution delay when a useraccidentally enters an incorrect hostname to the
ORB_init function (from a commandline parameter).
I ran my client code with trace level set to
25 and I see that there is a small delaybefore the getaddrinfo failure is
reported. The problem is that on some UNIXcomputers this delay is small (5
seconds in my sample output below) and on other computers this delay is many
minutes. There are many timeout settings available inomniOrb, however, the
symptoms make me believe that the delay is systemrelated.
I’m sure someone has encountered this behavior.
Can anyone point me in the right direction in order to address (or further isolate) the delay issue?
Thanks in
advance for any insight you can provide into this issue!The omniOrb output is listed below.
