Time from start to crash nscd service is max 1 hour.  

Strange messsage is after next start "nscd -d" on first debug row.

I did try swith off option with "peristent passwd no". Withou any result on

2.wait a while

Additional info:
Servers runing on 32bit architecture with same configuration and same RHEL with
updates haven't this problem - nscd run correcly.

I will try create core dump, or sent strace output.
Comment 1 Ulrich Drepper 2006-11-21 10:39:44 EST
The "invalid daatabase" might just be a consequence of the crash.  And everytime
the ldap nss module is involved chances are more than good that it is the problem.

Can you reproduce this with a better implemented NSS module?  Use NIS, it's
known to work.
Comment 2 Jakub Jelinek 2006-11-21 10:48:44 EST
Also, can you reproduce it with http://people.redhat.com/jakub/glibc/2.3.4-2.29/
(didn't get through QA yet, but for testing should be usable)?
There have been multiple nscd bugfixes since RHEL4 U4.
Comment 3 Jakub Jelinek 2007-03-19 06:20:51 EDT
Please retry with RHEL4.5 beta (glibc-2.3.4-2.36 or above) and reopen if the
problem still persists.
