enough, as this machine has 16GB of RAM, and /var is only about 9GB.
Obviously a pretty big oversight in the setup.  My question now is, can

Not at all, assuming you were not already mostly full.  When the
system crashes, only kernel memory is written to dump device (usually
swap).  Unless you have something really strange going on, this is
going to be a small fraction of the size of physical memory.  For more
details on the expected size of the the kernel core file, see InfoDoc
80249 (assuming you have a support contract...).

FWIW, on a very active (being pounded by Oracle) 15k domain with over
300 GB RAM, the biggest core that I have seen was about 17 GB.
Typically these systems will require somewhere between 6 GB and 12 GB
for a kernel core dump.
