Hmm, I wonder if putting this in a tmpfs might work around this.

Title:
  nscd crashes upon sudo when hosts caching is enabled (NIS, NFS)

Status in eglibc package in Ubuntu:
  New

Bug description:
  We use nscd in our diskless clients, but we've found regular evidence
  of crashes in our dmesg output, and I've been able to easily reproduce
  it by running sudo ls while hosts caching is enabled. The debug output
  when running nscd -d is as follows:

  Wed 17 Dec 2014 11:42:48 AM BRST - 3627: handle_request: request received (Version = 2) from PID 3649
  Wed 17 Dec 2014 11:42:48 AM BRST - 3627: 	GETFDPW
  Wed 17 Dec 2014 11:42:48 AM BRST - 3627: provide access to FD 5, for passwd

  Wed 17 Dec 2014 11:42:48 AM BRST - 3627: provide access to FD 9, for hosts
  Wed 17 Dec 2014 11:42:48 AM BRST - 3627: handle_request: request received (Version = 2) from PID 3649
  Wed 17 Dec 2014 11:42:48 AM BRST - 3627: 	GETAI (gasolinux)
  Wed 17 Dec 2014 11:42:48 AM BRST - 3627: Haven't found "gasolinux" in hosts cache!

  and then it dies.
