This could possibly be a problem with the switch, but one remedy would
seem to be to extend the time before the timeout kicks in (it seems to
be a few seconds at the moment). Any hints on how to achieve this?
That would depend on what you are booting. I suggest you ask in the
forum for the particular OS variant you are using. (Or at least tell us
what it is!)
Have a look at this
https://help.ubuntu.com/community/DisklessUbuntuHowto
especially the "gotchas" section and see if anything applies. My best
guess is that the NFS mount is taking too long to complete. It doesn't
sound like a switch issue if there is no problem with the PXE or tftp
parts.
Are you booting a bunch of nodes at once or one at a time, staggered?
All at once could bog down the head node so much that some compute nodes
time out.
