TomcatはJavaヒープスペースでのOutOfMemoryError（InvocationTargetExceptionが）

Question

はブラウザだけで簡単なフォームのPOSTアクションを行う持ち、Tomcatは以下好き

java.lang.OutOfMemoryError: Java heap space
java.lang.reflect.InvocationTargetException

を報告しています。しかし、1台のコンピュータ（すべてのブラウザ）がその問題を抱えているだけで、他のコンピュータは問題ありません。

You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set: 
    struts.devMode=false 
in your WEB-INF/classes/struts.properties file. 

私はTomcatに精通していません。ありがとうございました！

Answer 1

あなたがbin/の下であなたのtomcatディレクトリにsetenv.shスクリプトに次の行を変更する必要があり、あなたのTomcatに多くのメモリを追加したい場合は：あなたは10以上のPCのためのTomcatを実行-if、

export CATALINA_OPTS="$CATALINA_OPTS -Xms512m" 
export CATALINA_OPTS="$CATALINA_OPTS -Xmx8192m" 
export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxPermSize=256m" 

Answer 2

のような設定を試してみてくださいその： Tomcat8w.exe - > [Java]タブ - > [設定値（あなたが実行するために値を増やすことができます。）： 初期メモリ：512、最大メモリ：で、1-3pc -IF 2000

：1024は、スタックスレッド8GB RAMの追加 Javaオプション：-XX：MaxpermSize = 4096m 初期メモリ：4096、最大メモリ：4096、スレッドスタック：2048
