   > Please tell us, what you do in `JmeterMain#createNewFile`. If you are 
registering files via `FileServer`, you have to make sure to release them, once 
they are not needed anymore. Otherwise you might explode your heap, as your 
memory dump shows.
   
   `set HEAP=-Xms4g -Xmx4g -XX:MaxMetaspaceSize=256m`
   
   I registering files via` java.io.FileInputStream`,last night i use  
`fileServer.closeFiles();` to release is ok now, I guess there was a problem 
with Jmeter uploading the byte stream. The file in the store before the upload 
started, but there was no automatic release after the upload ended
