Hi, I've the same problem too, inside a jail, stored on ZFS. I've tried various tuning in slapd.conf, but none fixed the problem. While hanging, db_stat -c shows that all locks are being used, I've tried to set the limit really high, far more than normally needed, but it didn't help. I may have the same problem with amavisd-new but I've to verify that to be sure the symptoms are similar. I had no problem at all with the same setup on FreeBSD 8.2R, it was my most stable service back then. I've not tried with 9.0R.
