お忙しいところ申し訳ございませんが、対応方法が分からなかったためご質問させてください。
■環境
OS：windows server 2019
elasticserch-8.6.0
fess-14.6.1
■事象発生の流れ
上記の環境にて、elasticserch→FESSの起動ができることを確認。
下記の設定を修正。
①FESS_HEAP_SIZEの設定
bin/fess.in.sh
以下を3行目と4行目に追加
FESS_HEAP_SIZE=3g
②クローラ側のヒープメモリー最大値変更
app/WEB-INF/classes/fess_config.properties
・jvm.crawler.options-Xmxに以下を変更
#JVM options
-Djava.awt.headless=true\n
-server\n
-Xms128m\n\ ←削除
-Xmx1g\n\ ←1GBに変更
■エラー文（elasticsearch-8.6.0\logs\elasticsearch.log）
上記設定後、以下のエラー文によりelasticserchが起動しない。
エラー文らしき箇所を太字にしております。
