I posted this to openldap-bugs but I didn't see it actually posted to the archive so I'll try in openldap-technical. I have LMDB integrated and it's working smoothly except for this issue. ---- Original Message ---- I'm an author of an open source database called Sky (http://skydb.io/) and I'm interested in porting the backend off LevelDB and move it over to LMDB. I pulled down the LMDB code using the instructions on Ferenc Szalai's gomdb (https://github.com/szferi/gomdb) README: git clone -b mdb.master --single-branch git://git.openldap.org/openldap.git When I ran "make test" against the code it seems to run through most of the tests but I get a "Resource Busy" error at one point. Here's the full output: https://gist.github.com/benbjohnson/5628725 I'm running Mac OS X 10.8.3 and here's the output of my gcc -v: $ gcc -v Using built-in specs.
