Description Vojtech Moravek 2006-11-21 14:38:32 UTC

Description of problem:
NSCD service crashed while after start on 64bit x86_64 platform.
Time from start to crash nscd service is max 1 hour.  

Strange messsage is after next start "nscd -d" on first debug row. 
"invalid persistent database file "/var/db/nscd/passwd": verification failed"

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

Version-Release number of selected component (if applicable):
RHEL 4.u4
nscd-2.3.4-2.25
glibc-2.3.4-2.25 

Environment:
Openldap with 10000 users.
Samba server use ldap DB.
nscd provide passwd and group cache.

How reproducible:


Steps to Reproduce:
1.x86_64 arhitecture
2.wait a while

  
Actual results:


Expected results:


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 15:39:44 UTC

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 15:48:44 UTC

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 10:20:51 UTC

Please retry with RHEL4.5 beta (glibc-2.3.4-2.36 or above) and reopen if the
problem still persists.
