(ITS#8664) lmdb fragmentation leads to DDoS for consumers

If a back-mdb database becomes highly fragmented, it can spend a bit of time
trying to find an open slot for an incoming write op. If it is a master server,
this will cause all of its consumers to block all incoming read requests until
the write op is finished. It also blocks all requests to the master as well.
Once the page split completes and the write op is done, things go back to normal
until the next page split is required. In the case I'm looking at today, it
causes sporadic outages of 6-10 minutes for the master and all consumers. It
seems poor design that a write operation on the master will cause its consumers
to block all ongoing read operations until that write op is completed. A
temporary workaround is to stop slapd, export the DB via slapcat, remove the old
db, and then re-import via slapadd to eliminate the database fragmentation.
Example gdb backtrace of a consumer:

(ITS#8663) slapo-memberof cannot replace "olcMemberOfRefInt"
by quanah＠openldap.org
Full_Name: Quanah Gibson-Mount
Version: HEAD
OS: Linux
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (47.208.148.239)
While you can set olcMemberOfRefInt during an add operation when instantiating
slapo-memberOf with cn=config, you cannot modify the value after that point.
Attempting to change the value results in:
Running ldapmodify to change olcMemberOfRefInt value
ldapmodify failed (80)!

Actually no, this ITS is about tweaking back-mdb to give mdb_load a better
hint about what ordering to use. In particular, the id2v table in master/RE25
isn't being reloaded in proper order at the moment.

Yes, it was fixed in May of 2016 (2.4.44 was released February of 2016).
So it is already fixed for the next release (2.4.45).
Hope that helps.

I am not quite sure, if it is really the same problem. I do not use the
Red Hat openldap package.
I have downloaded openldap-2.4.44.tgz on January 5, 2017, and compiled
myself.

Thanks for the report, but this was already fixed in ITS#8218 released in
2.4.43. Sounds like Red Hat has botched their source code since the official
fix has been out for nearly 2 years already.
