The system had lots of RAM and swap available. The Normal zone was fragmented so no 64 KiB blocks were immediately available, but this allocation could have waited for defragmentation if needed. (Such fragmentation only occurs after the system has been running for some time, so I'm confident nfsd will successfully load if you try loading it shortly after booting.) Do you have any VM settings in /etc/sysctl.conf or /etc/sysctl.d? Ben. -- Ben Hutchings This sentence contradicts itself - no actually it doesn't.
