 Increase ''​pid_max''​ from ''​32768''​ to a larger number, such as ''​1048576'',​ like so: Increase ''​pid_max''​ from ''​32768''​ to a larger number, such as ''​1048576'',​ like so:
- sysctl kernel.pid_max +  ​sysctl kernel.pid_max 
- ​kernel.pid_max = 32768 +  kernel.pid_max = 32768 
- ​sysctl -w kernel.pid_max=1048576 +  sysctl -w kernel.pid_max=1048576 
- ​kernel.pid_max = 1048576+  kernel.pid_max = 1048576
    
 **NOTE**:​Sometimes the CRIU feature may cause similar trouble when it resets the PID to restore a process. This causes the PID to be reused too quickly, and can be a problem even with a large ''​pid_max''​ setting. **NOTE**:​Sometimes the CRIU feature may cause similar trouble when it resets the PID to restore a process.
