Today my Fedora Directory Server indices could not be updated anymore. Every
entry creation requiring an index modification (like adding an
inetOrgPerson entry, requiring modifying the index of
uid attribute) would fail with "operation error". In the ns-slapd
logs there was this message:
[31/Jan/2007:12:01:03 +0100] - libdb: Lock table is out of available object entries [31/Jan/2007:12:01:03 +0100] - libdb: Lock table is out of available object entries [31/Jan/2007:12:01:03 +0100] - idl_new.c BAD 50, err=12 Cannot allocate memory [31/Jan/2007:12:01:03 +0100] - database index operation failed BAD 1130, err=12 Cannot allocate memory [31/Jan/2007:12:01:03 +0100] - database index operation failed BAD 1140, err=12 Cannot allocate memory [31/Jan/2007:12:01:03 +0100] - database index operation failed BAD 1230, err=12 Cannot allocate memory [31/Jan/2007:12:01:03 +0100] - database index operation failed BAD 1030, err=12 Cannot allocate memory [31/Jan/2007:12:01:03 +0100] - add: attempt to index 12 failed
I tried to modify the DB_CONFIG files since I was thinking of a
Berkeley DB configuration issue. In fact the problem seemed to be linked with
the presence of temporary data files in the db/ directory.
[root@fedoracore6 slapd-fedoracore6]# ls db/ __db.001 __db.004 DBVERSION NetscapeRoot/ __db.002 __db.005 guardian userRoot/ __db.003 DB_CONFIG log.0000000001 [root@fedoracore6 slapd-fedoracore6]# rm db/log.0000000001 [root@fedoracore6 slapd-fedoracore6]# rm db/__db.00*
After a restart-slapd the problem was solved.
