その後のRaspberry Pi (RPi)の安定性<\/a>です。鉄壁の安定性を誇るRPi 4のmicroSDカード(SDカード)をクローニングしたRPi 3+はその鉄壁の安定性を受け継ぎ、今のところVLCによるRTSP動画再生のフリーズはありません1<\/a><\/sup>実際にはいろいろいじりながらなので今のところ1日以上連続運転することはないのですが，その間フリーズはありません．<\/span>。<\/p>\n\n\n\n

一方SDカードを新品と交換することで安定性が増加したRPi 3については、1日に数回フリーズと言う事はありませんが、1日もちません(半日内外でフリーズする感じ)。<\/p>\n\n\n\n

これを改善するにはそれこそ鉄壁の安定性を誇るRPi 4のSDカードをこちらにもクローンニングすればいいわけですが、そうすると多様性が失われてしまいます。もし次に何か重大なトラブルが起きたとき全滅と言うことになってしまいます。<\/p>\n\n\n\n

しかしその時はその時でクリーンインストールをすればいいだけの話で、今回は多様性を無視して全部クローンと言う形にして解決することにします。<\/p>\n\n\n\n
