the trace was done on the boot server where also the apache and tftp server
runs. This is another VM on the same ESX server.

If it helps I could post another trace of gpxelinux.0 4.04 which looks much worse.

I am also unclear as to why pxelinux 4.10 would not load vesamenu.c32 (UI
VESAMENU.C32) but try to load vesamenu.c32.0 and vesamenu.c32.com before giving up.

Kind Regards,
