More information is needed than this. Your stack traces aren't even complete. What was the workload leading up to this? Give us a sample configuration that reproduces the assert.

I came across what looks like this issue today. Let's see if I can provide more info.

I noticed one of my test machines (2.4.35) had crashed overnight. Unfortunately, I had neglected to set ulimit -c, so I had no core dump to work with. Upon restarting, however, I got the following:

slapd: ./../../../libraries/liblmdb/mdb.c:4025: mdb_page_search_root: Assertion `(((mp)->mp_pb.pb.pb_lower - ((unsigned) __builtin_offsetof (MDB_page, mp_ptrs))) >> 1) > 1' failed.

A backtrace shows that this occurred during an accesslog_purge(). The backtrace is at the end of this email.

The setup I have is a simple accesslog that records binds:

##### slapd.conf ##### ... database mdb suffix "cn=authstats" directory /apps/local/openldap-2.4.35/var/openldap-data/authstats maxsize 17179869184 dbnosync

rootdn cn=manager,dc=vt,dc=edu index default eq index entryCSN,objectClass,reqEnd,reqResult,reqStart

checkpoint 1024 10

overlay syncprov syncprov-nopresent TRUE syncprov-reloadhint TRUE ... # dc=vt,dc=edu overlay accesslog logdb "cn=authstats" logops bind logpurge 01+00:00 0+08:00 ... #####

If I comment out the logpurge line, slapd starts without incident, cn=authstats is queryable, and new entries are logged.

If I slapcat cn=authstats, remove the cn=authstats .mdb files, and slapadd everything back, upon startup the logpurge works as expected. If I move the original .mdb files back, the assert fails again.

I'm attempting to reproduce this starting with an empty accesslog. I have so far been unsuccessful. I do have the original .mdb files if they may be helpful (though they are around 1G).

One thing to note with the following backtrace is that the accesslog_purge() line number will be incorrect, as I have patched it to record connection info (like ITS#7345). None of this affects accesslog_purge(), though I can run these tests without the patch if necessary.
