There is in source code:

https://github.com/yuusuke/pacemaker/blob/efe2d6ebc55be39b8be43de38e7662f039b61dec/crmd/throttle.c


 switch(r->mode) {
        case throttle_extreme:
        case throttle_high:
            jobs = 1; /* At least one job must always be allowed */
            break;

and

throttle_handle_load(float load, const char *desc)
{
    if(load > THROTTLE_FACTOR_HIGH * throttle_load_target) {
        crm_notice("High %s detected: %f", desc, load);
        return throttle_high;


There are my log files:


Dec 16 04:51:09 server1 crmd[29851]:   notice: throttle_handle_load: High
CPU load detected: 8.010000
Dec 16 04:51:39 server1 crmd[29851]:   notice: throttle_handle_load: High
CPU load detected: 7.160000
Dec 16 04:52:09 server1 crmd[29851]:   notice: throttle_handle_load: High
CPU load detected: 6.980000
Dec 16 04:52:39 server1 crmd[29851]:   notice: throttle_handle_load: High
CPU load detected: 6.470000


So, main point of my issue  is  jobs = 1

Please,  does it possibly to increase number of jobs through  throttle high?
