Hello.
Today I run slapacl to test access rights and saw this: ldap3# sudo slapacl -F /etc/openldap/slapd.d/ ... ... 52a8ae51 mdb_opinfo_get: err MDB_BAD_RSLOT: Invalid reuse of reader locktable slot(-30783) read access to o: ALLOWED
At http://symas.com/mdb/doc/group__errors.html#ga1b6cbb28da30e28c48c9df66dd398b... I read explanation that this error means: Txn has too many dirty pages.
slapd 2.4.36 with Linux kernel 3.7.10 x86_64.
In my slapd I have single database with mdb backend: dn: olcDatabase={1}mdb,config ... olcDbNoSync: FALSE olcDbMaxSize: 1073741824 olcDbMode: 0600 olcDbSearchStack: 16
Two questions: 0. What might cause this error? 1. Should I worry about this?

Sounds like ITS#7662.

You need to read more carefully.

You should upgrade to get the fix for #7662.

Sounds like ITS#7662.
Could this problem affect replication, when consumer does not receive all data from provider (ACL allow replication account to access all necessary data)?

No, I need better sleep support.

I upgraded my slapd to 2.4.38, but I still see error message when I execute slapacl. I also removed data.mdb and lock.mdb, imported data back to ldap using backup copy and I still see error message.

Post your config, sample data, and the exact slapacl command you used.
