[squid-users] icmpRecv: Bad opcode: 0 error

I'm running 2.5.5 on an HP-UX 11.00 system and receiving the following
error message in cache.log:
  ...
  2004/12/15 10:28:00| icmpRecv: Bad opcode: 0
  2004/12/15 10:28:00| icmpRecv: Bad opcode: 0

  2004/12/15 10:28:00| icmpRecv: Bad opcode: 0
  ...

Squid is configured as follows:
  ./configure --enable-snmp --enable-icmp --enable-useragent-log
  --enable-refer er-log --enable-ident-lookups
  --enable-basic-auth-helpers=YP,getpwnam,PAM,LDAP
  --enable-external-acl-helpers=unix_group,ldap_group
  --enable-storeio=ufs,null

Any ideas? I don't get this problem on Solaris 9/SPARC.
