BTW, I'm using openldap 2.3.21 on freebsd and linux boxes. I use it
with bdb43. On all machines I have easy reproduceble problem -- if
slapd killing hardly he can't start. Eat all cpu, don't answer to
clients and can be killed only with -9 signal.
After running db_recover slapd start and work fine.
I look in ChangeLog. This issue not fixed in 2.3.2[23], or I'm wrong?
BDB 4.3 is a known problem release.  The suggested BDB release is
4.2.52+patches, and possible BDB 4.4.20+patches.  But not BDB

Ah, that's good to know. I upgraded an old 2.1.30 production server to 2.3.21 with bdb 4.3 and the load went through the roof, searches were blindingly slow, etc. I'm rolling back to 2.2.30 right now with db 4.2. We'll see if that fixes my speed problem.

Speaking of speed problem, I'm compiling db and openldap on a PIII 700.
I have a speed problem.  30 minutes to build it.  Heh.

Why would you use OpenLDAP 2.2.30 and not OpenLDAP 2.3.23? ;)
