I've checked 2.3.43 and 2.4.23; in both cases ber_int_sb_close() is being called twice on the same sockbuf. I suppose that might be considered a bug, but certainly the behavior has not changed between 2.3 and 2.4. > Following is the stacktrace: > [1] _libaio_close(0xffffffffffffffff, 0x2, 0x1, 0xffffffff7f300200, 0x0, > 0x0), > at 0xffffffff7f406a64 > [2] sb_stream_close(0x100151d80, 0x0, 0x0, 0xffffffff7f300200, 0x0, 0x0), > at > 0xffffffff7d21eafc > [3] ber_int_sb_close(0x100151d00, 0x0, 0x0, 0xffffffff7f300200, 0x0, 0x0), > at > 0xffffffff7d21e160 > [4] ber_sockbuf_free(0x100151d00, 0x1001497d0, 0x1, 0x1, > 0xffffffff7dbad2ec, > 0xd), at 0xffffffff7d21cebc > [5] ldap_ld_free(0x100149520, 0x1, 0x0, 0x0, 0x100117020, 0xdc3), at > 0xffffffff7d26a4bc > [6] ldap_unbind_ext(0x100149520, 0x0, 0x0, 0x1001219e0, 0x1001219f8, > 0x100121a00), at 0xffffffff7d26a048 > [7] ldap_unbind_s(0x100149520, 0x1001471d0, 0x100149520, > 0xfffffffffffffff2, > 0x0, 0x100117728), at 0xffffffff7d26a55c > ... > ... > > Thanks in Advance, > Asif Iqbal Desai > > -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
