Hi.
I have properly runnig setup of three multimaster OpenLDAP servers (version
2.4.36 from ltb project) with bdb database backend. Everything was working
flawless so I decided to try out ‚new shiny' mdb database with the same
configuration - the only thing I changed was removing ‚cache’ settings and
adding ‚maxsize’.
What I’m doing and observing:
- clear all config and database on all masters. Generate new configuration from
slapd.conf using ‚slaptest’ tool.
- on master1 I add three base organizations let’s say o=test1 + o=test2 +
o=test3 using slapadd [without -w switch]
- on master1 I add some entries using ldapadd command so all organizations have
now contextCSN attribute.
- starting master1 - everything OK
- starting master2 - everything OK, including succesfull replication from
master1
- starting master3 - everything OK and including replication, but… some or all
other master are dying unexpectedly.
strace of dying process show:
---
write(2, "slapd: id2entry.c:509: mdb_opinfo_get: Assertion `!rc' failed.\n",
63) = 63
This is ITS#7662. It was fixed a while ago but the fix was accidentally
omitted from releases. Fix will be in 2.4.38.

debug log last lines:
—
=> mdb_entry_get: ndn: „o=test1”
=> mdb_entry_get: oc: "(null)", at: „contextCSN"

But when I do ‚slapcat’ I can clearly see contextCSN for all o=test[123]
databases...
Is it bug or some possible replication configuration issue?
