Accounting server was alive and receving packets till yesterday. And suddenly got receiving dead alive messages. So restarted radiusd process then it got resolved.
 
However it repeating frequently once a week....
 
Unable to findout the exact reason for this.

Hi,

are you sure that the accounting server was ever alive and handling
accounting packets?  Those logs look exactly like they would if , for
example, you were sending auth+acct to an IAS RADIUS server not configured
for accounting.

the RADIUS server attempts to send an accounting packet to it...doesnt
get an accounting response. marks it as dead...has a timer, knows no
better than presume it alive and then back to step one. rinse and repeat
