If you use anon mmap, you won't have a file cache.mmap to check the size of. I'd also assume that the file would be maxMmap size all the time. > Linux is supposed to use anonymous mmap, but it still has problems > from time-to-time with corrupted cache.mmap files. If Linux is using an anon mmap, cache.mmap will not get corrupted because there won't be an anon mmap. > Julian: It'd be a good idea to incorporate code to validate > cache.mmap at startup and wipe/rebuild if it's corrupted. There are already some checks in there. However, if mmap() isn't reliable, not much is going to help. > AB Tom
