<desc>
Specifies the maximum size (in MB) for any core-dump of the
process.<br />
If this is negative, the default size of 1GB is used.<br />
If this is zero (or no value is set) then no limit is set.
If this is not set, the default size of 1GB is used.<br />
If this is negative, the size is unlimited.<br />
If this is zero then no core dumping is performed.
