Answer 1

A core dump or a crash dump is a memory snapshot of a running process. A core dump can be automatically created by the operating system when a fatal or unhandled error (for example, signal or system exception) occurs.

Answer 2

I was experiencing the same issue.

As, the error itself suggests -

Failed to write core dump. Core dumps have been disabled. To enable core dumping, try ulimit -c unlimited before starting Java again

ulimit gets and sets user limits. For more info on ulimit do -

man ulimit

So, open a terminal and run -

ulimit -c unlimited

This should solve the problem. To check if the change was successful, run -

ulimit -c -l

This should give you an output as follows -

core file size          (blocks, -c) unlimited
max locked memory       (kbytes, -l) 64

If the problem persists refer to this and this from askUbuntu.

Answer 3

For anyone seeing this issue from within Jenkins (as we are): To enable core dumps from jenkins, edit /etc/init.d/jenkins and add "--core" to $DAEMON_ARGS. Setting ulimit directly from the shell script or via /etc/security/limits.conf will not work.
