FEPCの再起動（予防的な措置）

概要: 
 長期間稼働するとハングアップすることがある件で、Dolphin未接続のFEPCを再起動しました。 
 あくまで予防的な処置です。必ずしも長期間稼働によりハングすることを示唆する意味ではない。
 Dolphin接続しているFEPCは次回再起動を行う予定です。

Restart of FEPCs (as a Preventive Measure)

Summary:
Due to the possibility of system hang-ups after prolonged operation, FEPCs not connected to Dolphin were restarted.
This is purely a preventive action and does not imply that a hang-up is certain to occur due to long runtimes.
The FEPCs currently connected to Dolphin are scheduled for restart at a later time.
