  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

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)?

I read explanation that this error means: Txn has too many dirty pages.

You need to read more carefully.

No, I need better sleep support.

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?

You should upgrade to get the fix for #7662.

Thanks, will try 2.4.38 today.
