EIGRP wierd issue

Hi

my network is running completely with EIGRP . today  one particular layer 3 device went down and came backup automatically by itself. when i see the logs i found that only that particualy layer 3 device went down. everything else was connected. i dont know why it that particular device alone went down and came backup

below are the logs

Hi

According to the message, it appears that the neighbor has terminated the connection (PEER-TERMINATION received)

have a look at the log in the neighboring router.
