There is just 2 tasks, a runimage and an osimage.
chain.currchain=osimage, and
chain.currstate=runimage=http://master/install/script.tgz.
The image is available to be downloaded. A nodeset on a single node
completed immediately.

How many tasks in your chain

What's the value of
chain.currchain and chain.currstate for nodes when you saw
that a lot of processes hang in 'nextdestiny' request?
What I can think of is the
'nextdestiny' will try to check the http download path of
'runimage', could you check the path is accessible from xCAT
MN? And could you run 'nodeset <node> runimage=xxx' to
see how much time it takes to finish?
Thanks

Subject: [xcat-user] Bad performance with 70
nodes requesting nextdestiny
Hi all,
My management node is experiencing a spike of over 60 load
when I boot
70 nodes at once and request a runimage of them. Doing a "ps
aux" shows
high iowait and what appears to be a perl process for
nextdestiny
running for each node. We had this same issue under xCAT 2.3,
and was
under the hopeful impression that performance was increased
with xCAT
2.8 and nextdestiny behavior.
After about 10 minutes it seemed to have chewed through the
requests and
the nodes continued their respective chained commands. Is
there a way of
improving the way the management node handles nextdestiny
requests from
10's of nodes at once?
Thanks!
