how to disable creating java heap dump after VM crashes?
문제
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.
해결책
If this is an OS crash dump then use ulimit to set the maximum core size to 0.
다른 팁
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
If you really mean a core file, and not something specific to java, then you need to use the ulimit command to set the maximum core file size to something small.
