Memory exhaustion in Ubuntu?

[justin...@gmail.com]

I'm trying to execute Jest on Ubuntu 14.04.02, in a virtual machine with 4gb of RAM. node version 0.12.2, npm 2.0.0-alpha-5

free shows me:

total used free shared buffers cached
Mem: 3.8G 199M 3.6G 976K 1.1M 18M

When I run npm test, I keep getting a variety of out of memory errors:

Error: FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory

FATAL ERROR: Committing semi space failed. Allocation failed - process out of memory

#
# Fatal error in ../deps/v8/src/heap/store-buffer.cc, line 132
# CHECK(old_virtual_memory_->Commit(reinterpret_cast<void*>(old_limit_), grow * kPointerSize, false)) failed
#

Any idea what the minimum memory requirement is...or if I have misconfiguration something that is leading to this?
