This command causes the optimizer to try to recover if it reaches 16 megabytes of data space.
This limit cannot be greater than the machine’s total available swap space, and in practice, should be small enough to permit normal use of the machine while a large compilation is in progress. For example, on a machine with 32 megabytes of swap space, the command limit datasize 16M ensures that a single compilation never consumes more than half of the machine’s swap space.
The best setting of data size depends on the degree of optimization requested and the amount of real memory and virtual memory available. To find the actual swap space:
hostname% /usr/sbin/swap
To find the actual real memory:
hostname% /usr/sbin/prtconf grep Memory
The
hostname% pc
