By default, the limit is set to eight. If your machine has enough RAM and CPU cores, and you want to go above this limit, you can change the limit using the `service.max_procs` configuration option. For each process instance, Tableau recommends that the machine running the process have at least 1 GB of RAM and 1 logical CPU core. To change the maximum number of processes allowed: 1. Type the following command, where `number` is the maximum number of process instances you want to allow: `tsm configuration set -k service.max_procs -v ` For example: `tsm configuration set -k service.max_procs -v 10` 2. Next type: `tsm pending-changes apply` If the pending changes require a server restart, the `pending-changes apply` command will display a prompt to let you know a restart will occur. This prompt displays even if the server is stopped, but in that case, there is no restart. You can suppress the prompt using the `--ignore-prompt` option, but this does not change the restart behaviour. If the changes do not require a restart, the changes are applied without a prompt. For more information, see [tsm pending-changes apply](https://help.tableau.com/current/server/en-gb/cli_pending-changes.htm#pending-changes-apply).
