You should consider testing with different BDB versions as well, as issues are known to slip into various updates. > Environment: > OS: CentOS 6.4 > OpenLDAP 2.4.36 > 1 Master w/ many syncrepl slaves

Subsequent read or write operations hang from all clients until slapd restart. slapd logs show: slapd[11213]: => bdb_idl_insert_key: c_put id failed: BDB0068 DB_LOCK_DEADLOCK: Locker killed to resolve a deadlock (-30993) slapd[11213]: conn=12787 op=25: attribute "entryCSN" index add failure slapd[11213]: => bdb_idl_insert_key: c_put id failed: BDB0068 DB_LOCK_DEADLOCK: Locker killed to resolve a deadlock (-30993) slapd[11213]: conn=13382 op=3: attribute "entryCSN" index add failure This issue has occurred sporadically for several months across different OpenLDAP versions. I managed to capture of a backtrace for two occurrences of the crash (excerpt below, full backtrace loloaded to FTP). In both instances, a couple of threads were acquiring locks which is where I suspect the issue lies.

(ITS#7948) mdb_copy insecure permissions
by geert＠hendrickx.be 24 Sep '14

24 Sep '14

Full_Name: Geert Hendrickx Version: 2.4.39 OS: centos6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (212.123.14.2) mdb_copy creates a copy using the default umask. This usually leads to insecure (world readable) copies, as typically an LDAP databse is 600 owned by some unprivileged ldap user. I suggest to copy the behaviour of cp, scp, rsync etc: preserve mode by default, preserve all metadata (uid:gid, mode, mtime, atime ...) when invoked with -p ?

This message is not an error, otherwise the situation would not be "ignored." > "mdb_load: line 6: unrecognized keyword ignored: db_pagesize" The mdb_dump format is a copy of BDB's db_dump format, which needs the db_pagesize.
