how to disable creating java heap dump after VM crashes?

Question

JVM runs on FreeBSD with 18Gb memory. creating core file takes about hour, which is very slow, so i need some way to disable it.

Answer 1

I'm not sure this will work, but if you're using the HotSpot VM, try this in the arguments to the java command:

-XX:HeapDumpPath=/dev/null

If you want to turn off core dumps altogether, you can use the ulimit approach (make sure to use the -H flag to set the hard limit):

ulimit -c -H 0
