Public bug reported:
Binary package hint: libnss-extrausers
If any /var/lib/extrausers/group entry has a gid 500 then all entries
from this file are ignored. libnss-extrausers-0.4 is affected as well.
The following file works fine, the entries appear in 'getent group'
output.
extra0:x:500
The problem is still present in Ubuntu 9.10. In my case the machine has
120MB of memory and 192MB of swap. Swap usage was about 10MB when the
following happened during heavy network IO:
[ 2489.732639] swapper: page allocation failure. order:0, mode:0x4020
[ 2489.732659] Pid: 0, comm: swapper Not
