KAP may require large amounts of memory in order to processes your
source code. The /heaplimit option specifies the
maximum size in megabytes that the KAP heap can grow. If this limit
is breached, KAP will stop processing your source code and try to
exit with an out of memory error message.
If you choose a /heaplimit setting that is greater
than the amount of memory that your machine has available, KAP may
run out of memory before it reaches the /heaplimit .
KAP relies upon the operating system to tell it that the process has
run out of memory before that problem occurs. Some operating systems
kill KAP without first telling KAP that there is insufficient
memory. In that case, KAP may stop processing your code and exit in
an undefined manner. Using /heaplimit makes a graceful
exit more likely.
