&gt; Hi,
&gt; 
&gt; I encountered OOM when I was using Dubbo 2.7.8
&gt; I find out that org.apache.dubbo.common.serialize.hessian2.Hessian2ObjectInput object can cause OOM。
&gt; 
&gt; the attachment is the patch for the above problem。it works fine on my machine。
&gt; 
&gt; I don't have permission to pull request，so I send this mail。
