OrientDB - 给定分区达到的最大池大小

我们有一个使用一组REST API的单页Web应用程序。 REST API层基于Jersey，它仅调用OrientDB REST API。我们通过OrientDB REST API调用OrientDB函数。

我们使用OrientDB 2.0.15

OrientDB不断地引发以下错误，即使连接

[OClientConnectionManager]Caught exception

很少数量我们已经下列属性设置

<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>

我们假定db.pool.min和db.pool.max设置服务器处理的最小和最大db实例。

我们也尝试用下面的性能;
