Hello, Aleksey.

Openldap 2.4.19 installed from freebsd ports. All configs in defauls Freebsd 7.2 amd64 Slapd built with the "-g" flag and install with the make install STRIP=""

Okay.

Used backends db46-4.6.21.4, db47-4.7.25.4 latest from freebsd ports.

   libdb-4.6.so.0 => /usr/local/lib/libdb-4.6.so.0 (0x800a97000)

At the same time? Your ldd list below shows only berkeley db 4.6. These don't mix...

In slapd config added using hdb as backend and indexes. Testing database consist of 1000 users accounts with minimum attributes. On stress test load slapd Segmentation fault in 10-30 sec.

What sort of operations?

Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x803404560 (LWP 100116)] 0x0000000802d5aa4b in hdb_idl_fetch_key (be=Error accessing memory address 0x7ffffd9f9f38: Bad s. ) at idl.c:511

Does it always fail at the same location? How reproducible is this?
