How to stop the creation of heap files, Java kernel files that are created in the JVM. Instance?

Question

In one instance of our server, heapdump, javacore, Snap files are created. How to stop creating these files. Please help me with this. Because heap files make our application slow and must remove it and reuse instances.

Answer 1

Your application is slow, possibly due to some memory problems. Disabling these dumps, although easy (just add a -Xdump:noneJVM argument ), will not solve the root cause of the problem.
