> I integrate IgniteClient into J2EE. In the HTTP-Request thread calls Ignite Service which the parameter's serialization is larger (about 100MB). By observing JVM console, I find that the memory occupancy is very bad. Through JVM dump, I find that ThreadLocal causes OptimizedObjectStreamRegistry.StreamHolder memory leak, which can be solved by the following modifications.
> org.apache.ignite.internal.util.io.GridUnsafeDataOutput#reset:
> {code:java}
> public void reset(){      
>     off = 0;      
>     out = null;      
>     // clear data
>     this.bytes = new byte[0];      
>     this.maxOff = 0;      
>     this.lastCheck = U.currentTimeMillis();
> }
> {code}
