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

Full_Name: Quanah Gibson-Mount Version: 2.4.44 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.148.239) 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.

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).

Thanks for the report, but this was already fixed in ITS#8218 released in 2.4.43.
