Hello, I've been trying past weeks upgrading my production openldap
software. I started from 2.4.11 when it was available, through all
available versions, up to 2.4.16. I tried package builds, and my own
builds. Each version except 2.4.10 was likely to hang, as it's
production, and load is quite high, I haven't too much patience to debug
and researching what's actually going on, but I tried disabling syncrepl
(no effect), some different settings for bdb backend and slapd thread,
concurrency etc ( starting from settings which caused no problems with
2.4.10 ), and finally, got back to 2.4.10 which works fine. Between
version change I noticed that 2.4.11+ is build with newer libdb versions
