Hi,

i've seen exactly the same on redhat EL AS3.0 on IBM Blade HS20 with
Openldap 2.1.30 and bdb 4.2.52. Hyperthreading is enabled in bios und i
am running a smp-kernel. slapd never can use more than 49.9% of the cpu
in total. 'top' shows these 49% spread over the 2 logical CPUs. Seems to
me as a problem of the 'top' implementation of AS3.0 (like other
problems with overflows in iostat under heavy io-load for example).
