nscd dead but subsys locked

Solution In Progress - Updated -

Issue

  • Server (out of around 100) every one week or so causes login issues and takes about 30min or so to login.
  • To resolve the issue, once login to that server and stop the nscd daemon and then everything comes back to normal state.
  • All the servers are running same OS installed from same kickstart image and hardware is also same but its causing problem on one server only.

  • Some preliminary information from that server:

[root@server1 ~]# nscd -V
nscd (GNU libc) 2.5
