Comment 11 for bug 256157

SRU justification:

impact:
 1. in use, nscd can frequently crash, thus denying caching, leading to higher network load and latency on lookups
  -> therefore high impact in a NFS and/or multi-user environment
 2. user may experience notification that nscd has crashed, compromising desktop experience

resolution:
 -> backported Ulrich Drepper's (glibc maintainer) upstream fixes for nscd corruption and crashing

patch:
 -> minimal patch attached

testcase:
 1. enable nscd in multi-user and/or NFS environment where multiple passwd and group lookups will occur
 2. generate lookups
 3. nscd may hit assertion after 2x garbage-collection intervals (~60s), else continue lookups

potential regression:
 -> none identifiable
