kernel-2.6.16-1.2171_FC6 : "Cannot allocate memory"

[sean]

Using kernel-2.6.16-1.2171_FC6 on amd64. On boot, both ntpd 
and nfsd fail:

Apr 29 14:14:13 localhost ntpdate[1877]: 
sendto(127.127.1.0): Cannot allocate memory
Apr 29 14:15:30 localhost nfsd[1914]: nfssvc: Cannot 
allocate memory

2.6.16-1.2153_FC6 works fine.

There some trick with the new kernel??
