2.4.36 is over a year old. Bugs reported against old releases will not be
investigated.

This is a normal occurrence in BerkeleyDB and does not indicate an actual
error. The bdb/hdb backend code automatically retries when a BDB deadlock is
reported.

When talking about BDB deadlock issues you should always obtain the output
from db_stat -CA on the db directory, in addition to the full stack trace.
You should consider testing with different BDB versions as well, as issues are
known to slip into various updates.

Upgrade to OpenLDAP 2.4.40, use back-mdb with a 64-bit OS, and dump the
deprecated and useless back-hdb/bdb.

(ITS#7951) slapd deadlocks during mod operation

Description: Slapd hangs during LDAP modification operation. 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.

Why don't you use a recent OpenLDAP version?
2.3.x has status historic for years and thus is not maintained anymore.
Ciao, Michael.

(ITS#7950) Memory leak issue
by kuldeep.itbhu＠gmail.com
Full_Name: Kuldeep Khare

Submission from: (NULL) (61.247.254.226)
Hi,
I am getting memory leak when calling below openldap api.
I am using openldap-2.3.31 version.
if(ldap_init())
{
ldap_configure_client(mSession,clientip);
int ldap_version = 3;
ldap_set_option(mSession, LDAP_OPT_REFERRALS, LDAP_OPT_OFF);
ldap_set_option(mSession, LDAP_OPT_PROTOCOL_VERSION, &ldap_version);
// set timeout for every complete search
ldap_set_option(mSession, LDAP_OPT_TIMELIMIT,
&SMA_CERT_LDAP_SEARCH_TIMEOUT);
// set timeout for any api call
struct timeval api_timeout;
api_timeout.tv_sec = SMA_CERT_LDAP_API_TIMEOUT;
api_timeout.tv_usec = 0;
struct timeval net_timeout;
net_timeout.tv_sec = SMA_CERT_LDAP_NET_TIMEOUT;
net_timeout.tv_usec = 0;
ldap_set_option(mSession, LDAP_OPT_TIMEOUT, &api_timeout);
ldap_set_option(mSession, LDAP_OPT_NETWORK_TIMEOUT, &net_timeout);
}
ldap_simple_bind(); //Only if init is successful
ldap_result(); //only if init is successful
ldap_unbind();
If anyone has encountered this issue please help.
Thanks,
Kuldeep

Never mind, due to a code change that affected a feature backport I have
privately. Closing this ITS.

After deploying OpenLDAP 2.4.40, slapd becomes completely unresponsive, and
every thread but the daemon is deadlocked

(ITS#7948) mdb_copy insecure permissions
by geert＠hendrickx.be

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 ?

Works as designed. This message is not an error, otherwise the situation would
not be "ignored."

The mdb_dump format is a copy of BDB's db_dump format, which needs the
db_pagesize.
Closing this ITS.

There may have been version skew, because the mdb_load command does not
understand the output of the mdb_dump command. See the following error in the
context below.
