Keepalive Tries
Range

Description
This is the number of consecutive keepalive failures that cause the 
trigger of a recovery procedure. A keepalive failure is counted 
when a keepalive timeout occurs and no response to the previous 
keepalive enquiry has been received. A lower tries count allows a 
more sensitive detection of failure, but with a higher chance of 
false trigger in high load conditions. A value of 0 disables the 
triggering of recovery procedures.

number of failures reaches this number, the board management 
function deactivates the board without doing the recovery 
procedure.
