System dump defaults

There are default agents for producing system dumps when using the JVM.

Using the -Xdump:what option shows the following system dump agent:
-Xdump:system:
    events=gpf+abort+traceassert+corruptcache,
    label=/home/user/core.%Y%m%d.%H%M%S.%pid.dmp,
    range=1..0,
    priority=999,
    request=serial
This output shows that by default a system dump is produced in these cases:
  • A general protection fault occurs. (For example, branching to memory location 0, or a protection exception.)
  • An abort is encountered. (For example, native code has called abort())
Attention: The JVM used to produce this output when a SIGSEGV signal was encountered. This behavior is no longer supported. Use the ABRT signal to produce dumps.
