Now I never found out why but both dhcp and authentication via winbind
(or ldap) to Active Directory seem to be broken in 8.04 (running ltsp
5). If you look back over the last few (4-5) months on this list
you'll find myself and one or two others found dhcp couldn't handle
more than about 5 clients booting at once (the clients would hammer the
dhcp server for multiple requests each), and our entire server would
grind to a halt if more than a few users tried to log in at once
(separate issues). We're authenticating to AD with ldap and also have
NFS shares set up like you, our load average on the server would soar
to 16 and beyond (2 dual core processors) and would never come down
again!
We went back to ltsp 4 again and everything seemed to run much much
faster. Now we're working to build another server and trying ltsp 5
again (on Debian) to see were things are.
No answers I'm afraid, but it sounds similar to what we found...

What authentication methods are you using? Are the users local or remote

Hi Steve,
I am using Winbind/Active Directory. Users have a home directory on
the server and a network share which is mounted via NFS.

Hi all,
I've been trying to migrate from 7.04 to 8.04 since last fall. I can
only do it during downtime at our school. I have this week while kids
are on break to try and get the new system in. My problem is that I
can't seem to scale the LTSP installation based on 8.04 past 6-8 thin
clients before the server crashes. The server is running 16 gigs ram/
AMD 64 image with Ntavo 6030 thin clients each with 512M ram. The thin
clients are rolled with the i386 image.
I can't find anything in the logs that shows me where the problem
lies. I've been running 7.04 successfully for a couple of years now
so I feel like the problem lies with 8.04 somewhere. I am trying to
decide whether to can 8.04 and begin working on 8.10. Or perhaps
retry 8.04 under 32 bit with the Server-Image kernel for larger memory
support. Can any one give me some guidance? Did you make 8.04 work
just fine (if so did you do it under 32 or 64) or did you end up going
for the latest and the greatest? All things being equal I'd prefer to
run 8.04 since it'll be supported till 2011.
Thanks for any advice.
John
