Perhaps telling us a little bit about your environment would help. Have
you opened a support call with Sun? What does authd being written in
Java have to do with anything? How many NIC's do you have active,
what's your topology? Are your switches blocking multicast? IPMP not
being a supported configuration has nothing to do with UDP.
If I were you, I'd open a call up with Sun support. /dev just doesn't
disappear. This forum is not a substitute for a support contract.

Hi all,
We setup two Sun Ray servers for a customer with about 50 users. There
has been lots of problem since it went live. I posted many questions on
this forum and got critical replies that had helped us to move ahead. I
will need help more than anytime.
Initially, our inexperience engineer setup the servers with IPMP on Sun
Ray public network. After knowing IPMP is not compatible with Sun Ray
probably due to the use of UDP multicast on multiple NICs in the Sun Ray
interconnect, we unconfigured Sun Ray and removed the IPMP
configuration. We reconfigured back the Sun Ray after that. Things went
smoothly for about a week and the servers (then in FOG) started to run
unstably. We suspected it was due to FOG after reading bug CR 6788938.
We decided to switch to standalone server and wait for the patch to try
again.
The standalone server went smoothly for about a week and problem started
to surface. There is once again intermittent stability problem primarily
on utauthd. I do not have the utauth log for every crash but it seems to
point to the following error:
05/01/2009 21:53:15 unable to join multicast group on bge0
05/01/2009 21:53:15 unable to join multicast group on bge2
05/01/2009 21:53:15 unable to join multicast group on bge3
Once that happens the device path (/dev) directory vanishes and
everything that relies on the path stop functioning. Can anyone help to
save my confidence in Sun Ray? I do not understand why the critical
piece of component utauthd is written in Java as well.
Thanks.
