Help! Would you recommend running ltsp on Ubuntu 8.04 or 8.10?

Hi Jonathan,

 I haven't been able to pull anything from the logs but the effect for
 end users it that the thin clients lock up. The Server is also
 unresponsive and I can't log in via ssh or on the console.

 The event that triggers the crash is having 10-12 students sign on at
the same time. Late last year I thought this might be related to
errors with NBD but no errors were logged to that effect this time
 around.   The system I have in place now (AMD 64, 4 cores, 32bit
 version of ubuntu 7.04) has 1/2 as much ram (8 gigs) and is much
 faster to logon, paint pages etc than 8.04. So much so that kids
 remark upon it. I am a bit flummoxed. I wish I didn't have to upgrade
 but 7.04 no longer enjoys software support :-(

Thanks for your ideas!

John
