Severity: 3-Major


During standard operation a process is expected to exit and be restarted once it has exceeded a certain memory limit. As a failsafe, the watchdog forcefully kills the process if it exceeds a higher threshold. But if the handler was running close to the memory limit before a resource-intensive event like a full sync load, this operation could push it over both limits.


A process may be killed in the middle of a data-integrity sensitive action, like a device-group sync, which can leave the system in a corrupt state.


An ASM Config handler is running close to the memory limit before a resource intensive event, like a full sync load.


Modify the memory limits in nwd.cfg to raise it by 100MB.
