back-meta hangs (ITS#3058)
Full_Name: Aleksander Adamowski

Submission from: (NULL) (157.25.5.68)
I have a setup where back-meta is used as a dynamic failover mechanism to
forward operations to 2 other OpenLDAP instances that are running back-bdb. It
listens on a port different than 389.
The relevant config options for the back-meta instance are (schema, access
control, TLS and SASL options omitted):
allow bind_v2 bind_anon_dn
pidfile /var/run/ldap/slapd_meta.pid
sizelimit 1024
threads 64
concurrency 36
database meta
suffix "dc=ourdomain,dc=pl,o=OurOrganization"
rootdn "cn=Manager,dc=ourdomain,dc=pl,o=OurOrganization"
rootpw {SSHA}CONFIDENTIALDATA
uri "ldap://localhost:389/dc=ourdomain,dc=pl,o=OurOrganization
ldaps://ldapreplica.ourdomain.pl"
# Legacy LDAP systems backward compatibility suffixes:
database meta
suffix "o=ourdomain.com.pl"
uri "ldap://localhost:389/o=ourdomain.com.pl
ldaps://ldapreplica.ourdomain.pl"
suffixmassage "o=ourdomain.com.pl" "dc=ourdomain,dc=pl,o=OurOrganization"
database meta
suffix ""
uri "ldap://localhost:389/dc=ourdomain,dc=pl,o=OurOrganization
ldaps://ldapreplica.ourdomain.pl"
About once in every 2-4 days back-meta hangs, and queries start to time out.
Usually only a few threads hang (it looks like they're deadlocked), so some
clients can receive results, and some are waiting for a reply until they
timeout.
I started running the back-meta instance in foreground mode on a screen session,
to have better control over it and more comfortable debugging. When back-meta
goes into the deadlock, and I press CTRL-C on its terminal, it starts exiting
cleanly, then ends up waiting for the deadlocked threads to terminate, e.g.:
<... multiple connections closing ...>
conn=148275 fd=89 closed
conn=149007 fd=98 closed
conn=148311 fd=102 closed
slapd shutdown: waiting for 4 threads to terminate
I have to kill the process manually to get rid of it and be able to start it
again.
I've attached with gdb to the slapd process, and extracted stacktraces for all
threads using gdb's command 'thread apply all bt'. Here are the results of 2
groups of stacktraces:
stacktrace group 1) When some back-meta threads are deadlocked, but before I
sent CTRL-C to slapd:
(no debugging symbols found)...Using host libthread_db library
"/lib/tls/libthread_db.so.1".
