며칠 후에 Tomcat 8.5가 응답하지 않습니다 – Liferay 6.1

Java 1.7.82에서 실행되는 Apache Tomcat 8.5와 함께 Liferay 6.1을 사용하고 있습니다. 며칠 후 Tomcat이 제대로 작동합니다! Liferay가 응답하지 않으며 이 문제를 해결하려면 Liferay를 다시 시작해야 합니다. 스레드 덤프에서 여러 스레드가 실행 중이지만 아래와 같은 유사한 스택이 있는 것을 볼 수 있습니다.

나는 이것이 org.tuckey.web.filters.urlrewrite 라이브러리의 버그라고 생각합니다. 이 문제를 조사했지만 유용한 것을 찾지 못했습니다.

Liferay 6.1 코드에서 다음 필터를 찾았습니다.

 <filter>
        <filter-name>UnsyncPrintWriter Pool Filter</filter-name>
        <filter-class>com.liferay.portal.servlet.filters.unsyncprintwriterpool.UnsyncPrintWriterPoolFilter</filter-class>
    </filter>
    <filter>
        <filter-name>URL Rewrite Filter</filter-name>
        <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
        <init-param>
            <param-name>logLevel</param-name>
            <param-value>ERROR</param-value>
        </init-param>
        <init-param>
            <param-name>statusEnabled</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>url-regex-ignore-pattern</param-name>
            <param-value>^/html/.+\.(css|gif|html|ico|jpg|js|png)(\?.*)?$</param-value>
        </init-param>
    </filter>

다음 설정에서 작동하는 것 같습니다 \portal-web\docroot\WEB-INF\urlrewrite.xml.

<urlrewrite>
    <rule>
        <from>(.*)/blog/blogs/rss(.*)</from>
        <to type="permanent-redirect">$1/blog/-/blogs/rss$2</to>
    </rule>
    <rule>
        <from>(.*)/-/blogs/rss\?&amp;(.*)</from>
        <to type="permanent-redirect">$1/-/blogs/rss\?$2</to>
    </rule>
    <rule>
        <from>^/c/journal/view_article_content\?groupId=14&amp;articleId=155291$</from>
        <to type="permanent-redirect">/web/guest/home/-/journal/rss/14/news</to>
    </rule>
    <rule>
        <from>(.*)/tunnel-web(.*)</from>
        <to type="permanent-redirect">$1/api$2</to>
    </rule>
    <rule>
        <from>^/web/guest/community/forums/message_boards(.*)$</from>
        <to type="permanent-redirect">/web/guest/community/forums/-/message_boards$1</to>
    </rule>
    <rule>
        <from>^/web/guest/home/journal/rss/14/news$</from>
        <to type="permanent-redirect">/web/guest/home/-/journal/rss/14/news</to>
    </rule>
</urlrewrite>

버전 은 urlrewrite.jar2.6.0입니다.
