Unfortunately, Cygwin is only a 32-bit application, so even when running on a 64-bit machine it is limited by the 4GB address space of a 32-bit process, the upper 2GB of which are reserved for the OS kernel, and of the lower 2GB, the various Windows and Cygwin DLLs use a lot of the upper 1/2GB of that. > We also tried with ulimit –v option , and we are not able to change the vm > size , it says 2 GB is the MAX! You could try setting the VM's boot configuration to include the /3GB and /PAE switches, but that only might help gain a bit more headroom; the fundamental 32-bit-ness of Cygwin (and hence all Cygwin applications) would take probably something up to a few person-years of work to change. cheers, DaveK -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
