On old Linux systems LispWorks (64-bit) for Linux has range 192GB, ending at
, because old Linux systems cannot map above
and put the dynamic libraries just below that limit (at least in some configurations). Since LispWorks uses the address space sparsely, it will run out of memory with less virtual memory, probably around 150GB to 160GB. If more memory is required, the range can be extended downwards, and possibly some distance upwards too. If other software uses memory in the range from
, LispWorks should be relocated (potentially just by decreasing the range) to avoid memory clashes.
Modern Linux systems have a much larger address space and the default size of the LispWorks range is
