According to the docs the `Number of simultaneous users to group by` is: "Number of threads to release at once. Setting it to 0 is equivalent to setting it to the Number of threads in the thread group".
Therefore, if you want the synch timer to trigger using 100 threads you should set this value to 100. If there are only 100 threads in the thread group, and if one of these threads stops because of an error, then it is logical that the timer is never triggered because it will never see 100 threads running. What you could try is: 1. Increasing the number of threads in the thread group to, say 110, and keeping the synch timer set to 100, in the hope that this adds some robustness. (Not ideal.) or 2. Changing the `Action to be taken after a sampler error` in the thread group to something like `Start Next Thread Loop`. Of course, these values depend on the wider context of your test but I would imagine you can get the effect you need by playing around with them.
