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.
