 Andrew,
 
 I run 6.2-RELEASE on an Ultra60 (2-way SMP), with nfsd running although
 not actively serving any NFS clients.  I am also not running Apache, as 
 you are.
 
 I am able to ping this machine (I receive an ICMP_ECHOREPLY [id=0] packet
 back corresponding to each ICMP_ECHO [id=8] packet I send to the machine.)
 
 Are you familiar with ddb and kernel debugging at all?  If so, find out 
 exactly what the kernel is doing with those ICMP_ECHO packets.  They would 
 be stored in mbufs by the kernel after the NIC DMAs them into main memory.
 
 Watch those mbufs during breakpoints on various network functions. 
 If I were you, I would start by setting breakpoints on ip_input() and icmp_input().
 
 Regards,
 
  	Jon
