| Notes |
| + |
By default, Samba 4.10 is run using the "standard" process model which is one-process-per-client. (Later versions use 'prefork'). |
| + |
This is controlled by the -M or --model parameter to the samba binary. |
| + |
All Samba versions are impacted if -M prefork or -M single is used. To mitigate this issue, select -M standard (however this will use more memory, and may cause resource exhaustion). |
