Description Noriko Hosoi 2009-03-19 20:51:43 UTC 
Description of problem:
Reported by Neuron Ring.
1. I need to merge to input files using mmldif tool
2. I m exporting it to a ldif file using db2ldif tool

/opt/dirsrv/slapd-<instance1> /db2ldif -n <backend_instance1>
/opt/dirsrv/slapd-<instance1> /db2ldif -n <backend_instance2>

3. I got two ldif files by exporting two directory server instance databases.
One.ldif
dn: sn=Jensen,dc=siroe,dc=com
objectclass: top
objectclass: person
cn: Babs Jensen
sn: Jensen
telephoneNumber: 555-5550
createTimestamp: 100

dn: sn=Minsky,dc=siroe,dc=com
objectclass: top
objectclass: person
cn: Pete Minsky
sn: Minsky
telephoneNumber: 555-5551
createTimestamp: 100

dn: sn=Rose,dc=siroe,dc=com
objectclass: top
objectclass: person
cn: Paula Rose
sn: Rose
telephoneNumber: 555-5552

Two.ldif

dn: sn=Jensen,dc=siroe,dc=com
objectclass: top
objectclass: person
cn: Babs Jensen
sn: Jensen
telephoneNumber: 555-5550
createTimestamp: 100

dn: sn=Minsky,dc=siroe,dc=com
objectclass: top
objectclass: person

sn: Minsky

sn: Morris
telephoneNumber: 555-5558
createTimestamp: 200

dn: sn=Rose,dc=siroe,dc=com
objectclass: nsTombstone
deleteTimestamp: 200

4. Now I m trying to use mmldif tool.
5. /opt/dirsrv/bin/mmldif -c -D -o /home/neuronring/output.ldif   /home/ neuronring/one.ldif   /home/ neuronring/two.ldif
6. Finally everything IN VAIN, I got the following error: 

[18/Mar/2009:11:35:04 +051800] - finger printing directory 0
[18/Mar/2009:11:35:04 +051800] - db0: dn: sn=Jensen,dc=siroe,dc=com
/opt/dirsrv/bin/mmldif[50]: 18247 Memory fault(coredump)

The following files are created in my path. 
1. one.ldif.delta
2. two.ldif.delta
These two files has no data 0 bytes size.
3. core – size 1882552 bytes

Even I tried exporting the database with –r option (for replica) after stopping the instance. I m getting this error continuously with different error numbers like, /opt/dirsrv/bin/mmldif[50]: 10854 Memory fault(coredump). 

Somebody please suggest me to resolve this issue.

Thanks in advance,
Neuron Ring.

Cause: secmod module list / module list lock is NULL.

cvs diff ldapserver/ldap/servers/slapd/tools/mmldif.c

Description: NSS was not initialized.  Since cert db, key db, or secmod db are not needed, changed to call NSS_NoDB_Init to initialize NSS.
