You don't say what OS you're using, so I'll have to be very general. It means you've run out of virtual memory. You need to increase the space. It's called a "paging file" in Windows and "swap partition" in Unix/Linux. Note you can also use a file for swap space in Unix, but the traditional allocation has been a separate disk partition.
When disk was expensive, the rule of thumb was swap = 4 X DRAM. However, disk is now so cheap I use swap = 8 x DRAM. If you don't need the space it has no effect on performance. It's just wasted disk space. DRAM is hundreds of times faster than a hard drive, so there's a big performance hit if you start paging. If you can't add more DRAM to your system, adding a solid state disk for swap space will be much faster than a regular hard drive. Have Fun!
