Gerrit - thanks for your reply.
In looking at the boot.ini snip, it looks like it is related to the size of
disk partitions being greater than 2GB.
I'm referring to a limit on the RAM/Memory that cygwin appears to impose.
My server has 8GB of RAM, but cygwin sees only 2GB of it according to
vmstat and top commands running in the cygwin bash shell.

There is a Windows limitation, no application may allocate more then 2GB
unless you specify the right value (e.g. /3GB) in the boot.ini file.
boot.ini example:
[Boot Loader]
Timeout=7
Default=scsi(0)disk(0)rdisk(0)partition(1)\WINNT
[Operating Systems]
scsi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows 2K Server" /3GB
scsi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows 2K Server [VGA-Modus]"
