Full_Name: Quanah Gibson-Mount Version: 2.4.43 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.148.239) When using glued/subordinate databases, the "limits" directive needs to be set on the parent as well as subordinate dbs to be applied if there are global limits in place. This is currently not documented. Otherwise, the "limits" directive settings on the subordinate databases is not honored.

(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.
