+其它模块复用了 Common 层的基于文件的缓存机制（目前是元数据模块），而 Common 层的文件缓存机制 “发觉” 条目超限。
+显示的例子如下：
+
+## 可能的原因
+1. 用户不合理地配置了 Java System Property （用 -D 配置的 Java 系统属性） 
`dubbo.mapping.cache.entrySize` 或者 `dubbo.meta.cache.entrySize`
+
+{{% pageinfo %}}
+
+**提示：**
+`dubbo.mapping.cache.entrySize` 或者 `dubbo.meta.cache.entrySize` 的默认值如下：
+
+<style>
+    .sheet-border, .sheet-border tr, .sheet-border tr td {
+        border: 1px black solid;
+        text-align: center;
+    }
+
+    .sheet-border tr td {
+        padding: 0.5rem 2rem;
+    }
+
+    .sheet-header td {
+        font-weight: bold;
+        background: #cccccc;
+    }
+</style>
+
+<table class="sheet-border">
+    <tr class="sheet-header">
+        <td>dubbo.mapping.cache.entrySize</td>
+        <td>dubbo.meta.cache.entrySize</td>
+    </tr>
+    <tr>
+        <td>10000</td>
+        <td>100</td>
+    </tr>
+</table>
+
+{{% /pageinfo %}}
+
+## 排查和解决步骤
+1. 尝试重新配置上述 **Java System Property（用 -D 配置的 Java 系统属性）**。
+2. 如果确实没有配置这些 System Property，请到 [GitHub Issue 
Tracker](https://github.com/apache/dubbo/issues) 下发 Issue。
