going through the logs, after it happened again, I got a glimps of this:

Feb  6 18:00:13 warhol-00.cs.huji.ac.il kernel: bce0: discard frame w/o 
leading ethernet header (len 0 pkt len 0)
Feb  6 18:00:19 klee-05.cs.huji.ac.il kernel: nfs: server warhol-00 not 
responding, timed out
...
Feb  6 19:00:00 warhol-00.cs.huji.ac.il amd[715]: More than a single value for 
/defaults in hesiod.local
Feb  6 19:00:00 warhol-00.cs.huji.ac.il amd[715]: Unknown $ sequence in 
"rhost:=${RHOST};type:=nfsl;fs:=${FS};rfs:=$huldig<C0>#^ZM-^KoM- abase"
Feb  6 19:00:00 warhol-00.cs.huji.ac.il kernel: impossible packet length 
(2068989523) from nfs server sunfire:/dist
