NetBSD rugged 8.99.1 NetBSD 8.99.1 (GENERIC) #7: Mon Jul  3 15:56:30 CEST 2017  root@chieftec:/public/netbsd-root/sys/arch/amd64/compile/GENERIC amd64
Files /proc/pid/map and /proc/pid/maps cannot be read for large applications.

pmap(1) works.

$ pmap -p 1039|wc -l
Determine the pid of Firefox.

$ cat /proc/1039/map                                                                                                           
cat: /proc/1039/map: Cannot allocate memory

$ cat /proc/1039/maps
cat: /proc/1039/maps: Cannot allocate memory

It would be nice to remove the limit at all.
