Hi Ben and David
Here we are having a similar problem.
We had setup 2x SFV240 with Solaris 9, SRSS 3.1, patch 120879-05 and
configured failover group. Our SunRay clients consist of SR150, SR170,
SR1g and tadpole. All of the SR clients firmware were updated to version
3.1. The SunRay clients were connected to Cisco Core SW 4507 -
10/100/1000 module.
Few months back, all of sudden, all of our SR170 were having
disconnected and reconnected randomly( occasionally ). After their SR170
reconnected user have to retype username / password and they got
sessions back. But only three(3) SR170 were in severe problem which is
continuously disconnect and reconnect and all over again.
Any idea what is happening in our environment ?
Any help will be appreciated. Thanks.
# Yours Sincerely,
# Mohamed Ali Bin Abdullah.

Hi all,
For one of the setups I made in the past months, the client seems to
experience a strange problem. The setup is made with a Sun Fire V240,
Solaris 10 11/06 with latests patches, SRSS 3.1 + uttsc 1.1 with latests
patches (the firmware of the DTUs has been upgraded recently as well). DTUs
used are all SunRay 2 and SunRay 2FS.
Without any apparent reason, randomly, one DTU at a time, the session is
lost on the DTU, and then it come back. User have to put back his login /
password for logging in Windows environment, and he can go back to the
previously opened applications. When it happens to a DTU, others are
working properly without any problem, and nothing is done at the time on the
SunRay server.
I never saw this before, nor with SunRay 1, 1G, 2 or 2FS... Actually, I
suspect this might be a network related problem. The network on the
client's side seem to be not that good, but is there a way I could verify
it? Is anyone has experienced something like that before? Any clues?
Thanks in advance!
Ben Audet

Ben,
I concur that it sounds like a network issue. I have had this happen when
there is a high latency and packet loss. Run the command
/opt/SUNWut/sbin/utcapture and you will be able to see if this is your
problem. Are you running a shared or dedicated enviroment? Dedicated
networks or vlans are allway better to isolate your DTU's from WAN traffic.
Good Luck
