Its limited only by the hardware and OS you are running. Some OS's on
32bit allow for up to 4 gigs but you have to leave room for the OS and
other running processes. On 64 bit hardware it can be limited by the
Hardware along with OS where its artificially limited to 32gigs, 64 gigs
and 2TB seem to be the most common limits set by the hardware or OS.
But again you have to leave room in these setting for other processes if
not out memory errors will occur and may crash the server.

In general these setting are only limited by the Hardware and OS
