Some kernels don't have "large" file support. The issue is, I think, related to the size of an integer. On my x86 (Duron 750) processor, maxint is 2147483647 with is (2**31)-1. Thus I have 31 bits (though the C constant INTBITS says 32) for storing integers. A gigabyte is 1024 megabytes, which is 1024 kilobytes, which is 1024 bytes (powers of 2). Thus a gigabyte is 1073741824, and 2 gigabytes is 2147483648. 2**32 == 2GB. Thus 2GB is the limit of indexable bytes in a 32-bit system. I think this is the cause of the results you are seeing. It may work if you split it into 2 2GB partitions and mount both of them as swap. HTH, -D -- A)bort, R)etry, D)o it right this time
