[KevinS@bmrb.co.uk]

Okay, thanks for the pointers.  now running a slapd compiled with debug
symbols, without optimization and not stripped.

Heres the backtrace from that thread when slapd is under load from
ldapsearch...
#0  0xff01fb74 in time () from /usr/lib/libc.so.1
#1  0x00176eac in ldap_pvt_runqueue_resched (rq=0x2f6388,
entry=0x9489c48,
    defer=0) at rq.c:174
#2  0x000494b0 in slapd_daemon_task (ptr=0x0) at daemon.c:1797
#3  0xfef157bc in _lwp_start () from /usr/lib/libthread.so.1

and heres what its doing after the searches have completed...
#0  0xff01db44 in _poll () from /usr/lib/libc.so.1
#1  0xfefd2a08 in select_large_fdset () from /usr/lib/libc.so.1
