OL 2.3.27 doesn't work with BDB 4.5, although I (so far) have not been able to track down a BDB 4.5 specific commit to HEAD. --Quanah -- Quanah Gibson-Mount Principal Software Developer ITS/Shared Application Services Stanford University GnuPG Public Key: http://www.stanford.edu/~quanah/pgp.html

I think Michael just has a corrupt build tree. The previous issue he reported was cleared up by running "make clean" in the back-bdb and back-monitor directories, then rebuilding. I suspect just doing a "make clean" from the top level and rebuilding would clear up the rest. This does point out a bug in the slapd Makefile; for dynamic backends it appears to not remake the backend directories if they have already been built once. I'll look into that... -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc OpenLDAP Core Team http://www.openldap.org/project/

Maybe try without optimization? Yes, I learned this (again) on Friday. ;-) export CFLAGS="-g" But it still does not work. Ciao, Michael.

Linux stops when reached 2GB file out; but there was a little bit of memory available and the allocation rate was similar to previous trials In Solaris, due to speed up the test I've ulimit -d 1024000, reached 2 GB file without stops itself (usually solaris continues, simply throws out additional data) then some time later: ch_malloc of 16392 bytes failed ch_malloc.c:57: failed assertion `0' Abort (core dumped) with a while/loop ps, last line was: PID RSS VSZ %MEM TIME STIME COMMAND 18246 1652488 1656144 41.1 31:23 09:22:35 slapcat > On my linux 2.6 system (64 bit), with a 2.5 million entry db, which > is: > > ldap00:/var/lib/ldap/slamd/64-2.5mil-db42# du -h *.bdb > 84M cn.bdb > 618M dn2id.bdb > 85M employeeNumber.bdb > 3.2G id2entry.bdb > 3.7M objectClass.bdb > 85M uid.bdb this runs I've tried a db like: ldap@labsLDAP:/TEST_producer/openldap-data> du -h *.bdb 3,0M testCode.bdb 2,9G dn2id.bdb 600M entryCSN.bdb 545M entryUUID.bdb 15G id2entry.bdb 1,9M objectClass.bdb 270M testId.bdb > So, that does mean one thing -- It definitely outgrew the 366MB of BDB > cache defined.

The preferred use consists in creating the socket according to umask in a directory with the desired permissions. Right now, those permissions are used to coarse grain regulate operations on a specific listener; considering their limited usefulness, their use is not recommended as that extension could be removed. It's considered experimental. > With the attached patch, PF_LOCAL sockets are always created world-writable by > setting the umask to zero before bind().
