Hi,
These files are getting generated because your JVM is getting crashed frequently.
When JVM crash, JVM captures the state of the JVM at the time of crash and these files generate.
Please study your std_server log very carefully and you will find some lines like "Out of Memory" kind of error.
Now if you can stop the crash of the JVM, these files wont generate any more.
I have faced the same issue and Fix it using the following ways.
1)  Upgrade your JVM to the latest version so that better memory management will be in place.
2) If still these files getting generated, you can tune the new version of the JVM.
