I used to import File::Map to handle a file as if it was a normal scalar variable and it used to work fine. Yet recently I encountered a memory allocation error.
Could not map: Cannot allocate memory at -e line 1. The only difference I see is that the file is quite large: about 2Go, and I have about 1Go of RAM + 2Go Swap. Yet I don't understand why this should be an issue. map_file is not supposed to load the whole file in memory, is it? I also noticed that there is a more standard perl module called Sys::Mmap that does the same thing. But it also gave me a memory allocation error. What is the proper way to tie a large file to a scalar variable? In reply to mmaping a large file by grondilu
