Re: Need to know the sugnificance of maxdsiz and maxdsiz_64bit Kernel parameters

These are fencs to prevent runaway programs from using all of virtual memory. maxdsiz controls the maximum size the data area can be in a 32 bit program. Default is 64megs, max is 970 megs or 1750 megs when using the EXEC_MAGIC capability of quadrant mapping.

maxdsiz_64 controls the maximum data size of a 64bit program.

As with all kernel parameters, there is online help in SAM for these parameters.
