Hi Nicolas,
First off, thanks for your kind help!

Dear Nicolás,
Recently we moved the Sun Ray clients to run against the production
server, resulting in some of them running a graphic session without
any faults, and some of them stucking in the '26D' screen. [...]
I read that this could be due to the inability of renewing the DHCP
lease, however, the SRS server is *not* configured as a DHCP
server, we have a dedicated server for that.
unfortunately I do not have a good idea what would might cause such
logs. But I'm trying to ask some questions, hoping that one of them
might be helpful in searching further...
- Did you check that your DHCP server is still working as expected?
Might some IPs be assigned non-exclusively?
Yes, it is. I must emphasize that we don't use the Sun Ray's DHCP server
(utadm), but a dedicated server for DHCP purposes and it's working fine
all time. I don't think there might be an IP conflict, as the IP
addresses for our clients are all bound by their MAC address.
- Does the 'realIP' (0adb08e8=10.219.8.232 in your log example) stay
the same or change according to your DHCP configuration?
It's always the same for each client address, that's the weird thing.
However, I've been looking for some extended information about this and
I see people having this problem in the middle of users' session. In our
case, it just happens when someone restarts the Sun-Ray client or logs
out (as far as we have seen up to now).
- If you trace the network traffic for a particular 26D-client: can
you verify the connection loss as it is claimed by the server log?
That's something I've not tried yet and it's a good idea, I'll try to
trace the traffic for that client and verify what kind of traffic is
being sent between client and server. I've seen this is an issue that
formerly appeared in 2010 but has not a clear diagnosis yet, and I don't
know clearly how to force it for reproduction, but indeed once I do I'll
try and post some updates.
I've seen a similar issue on a blog which talks about some mess with the
ARP table on the server side
(http://www.planetgeek.ch/2012/04/02/sunray-terminal-unexpected-reboot/). I'll
try to check the ARP table as well and see if it helps determining the
problem.
Again, thanks for your help!
Regards,
Nicolás
Good luck and kind regards,
Nicolas
