I cloned the git repository "git://git.openldap.org/openldap.git", then I compiled this version "2.X" as specified in the 1st message. Please consider that, after recompiling this version, I rebooted the server where slapd is running.
As far as I can see, it seems the memory consumption is the same as 2.4.42: it starts to increase up to 60%. In fact, with gdb, I got now an assertion failed due to:

So, a malloc failed returning NULL. This happens also with the 2.4.42.
Now I relaunch again the loading procedure and see what's happening.
2015-10-28 16:41 GMT+01:00 Michael Str=C3=B6der michael@stroeder.com:
Any chance for you to test RE24 branch with the code to be released as 2.4.43?
There were some fixes for crashing syncrepl added therein.
Ciao, Michael.
