In more seriousness, where should this be documented? I found a couple of good posts, the best being DJ's: http://sources.redhat.com/ml/cygwin/2000-04/msg00267.html (though I believe the 'normal' max is now 256MB). His test program (on my machine with 256MB physical memory) gives: $ ./maxmem.exe 1b5a4000 bytes (437.6Mb) Perhaps a good place would be in the User's Guide under the discussion of shared memory in the "Highlights" section. Something like: "By default Cygwin imposes a 256MB memory limit. To raise this limit, you may create a "heap_chunk_in_mb" registry entry, for example: regtool -i set /HKCU/Software/Cygnus\ Solutions/Cygwin/heap_chunk_in_mb 512 You will then need to reboot for it to take effect." -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
