OrientDB - 給定分區達到的最大池大小

我們有一個使用一組REST API的單頁Web應用程序。 REST API層基於Jersey，它僅調用OrientDB REST API。我們通過OrientDB REST API調用OrientDB函數。

我們使用OrientDB 2.0.15

OrientDB不斷地引發以下錯誤，即使連接

[OClientConnectionManager]Caught exception

很少數量我們已經下列屬性設置

<properties> 
    <entry value="50" name="db.pool.min"/> 
    <entry value="500" name="db.pool.max"/> 
    <entry value="false" name="profiler.enabled"/> 
    <entry value="info" name="log.console.level"/> 
    <entry value="fine" name="log.file.level"/> 
    <entry value="10000" name="storage.record.lockTimeout"/> 
</properties>

我們假定db.pool.min和db.pool.max設置服務器處理的最小和最大db實例。

我們也嘗試用下面的性能;
