Any Ideas not including aiodone is a hack.

        case LSSLEEP:
            if (l->l_priority > PZERO || l->l_slptime > 1)
                continue;
is there just to add io blocked lwp to the load, but aiodone allway 
sleeps with l_priority < PZERO.

        avg->ldavg[i] = (cexp[i] * avg->ldavg[i] +

Hi,

the loadavg is almost to high, the problem is the aiodone daemon 
sleeping with l_priority < PZERO.
I think the aiodone daemon should not be acounted for by the loadavg 
calculation.
Or can it sleep with l_priority == PZERO
