Spring boot Thymeleaf间歇性抛出TemplateInputException和TemplateProcessingException

我有一个springboot（2.1.0.RELEASE）webapp，我使用Thymeleaf作为模板引擎。 在一页中，我间歇性地出现以下错误。 如果我重新启动服务器或几小时后，这个错误通常会消失

2019-10-09 17:18:51.198 ERROR maa1n12-stg-004 --- [.1-6551-exec-51] o.s.b.w.s.s.ErrorPageFilter              : Cannot forward to error page for
 request [/testExecutionResponse/getResponseByExecutionId/8517] as the response has already been committed. As a result, the response may have 
the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ib
m.ws.webcontainer.invokeFlushAfterService to false

错误中提到的代码是

<tbody>
    <tr th:each="i : ${#numbers.sequence(executionSummary.size() - 1, 0, -1)}"
        th:with="summary=${executionSummary[i]}"
                th:classappend="${#strings.equals(summary.state,'SUCCESS')} ? 'alert alert-success' : 'alert alert-danger'">
                <td th:text="${summary.state}"></td>
                <td th:text="${summary.result}"></td>
                <td th:text="${summary.errorCategory}"></td>
                <td th:text="${summary.count}"></td>
        </tr>
</tbody>

我无法找到问题的根本原因

PS：这不是内存问题，因为所有其他组件都工作正常，内存使用率约为15-20%
