Opened: Nov 20, 2018
Severity: 2-Critical


When manually copying a large config file and running 'tmsh load sys config' on specific hardware BIG-IP platforms, multiple cores may be observed from different daemons.


The mcp daemon may core and all daemons on the BIG-IP system may be restarted.


This has been observed on i4800 platforms when the 'management' provisioning (corresponding to the provision.extramb DB key) is set to 500 MB or less.


Set db key 'provision.extramb' to 1024 or greater.
