The number of kernel modules has been increasing quite quickly, and
modules are installed with the kernel (by default).  This has led to
installkernel filling up the root filesystem increasingly often.  It
just happened to me yesterday, although in that case snapshots and four
or five old kernels were part of the problem.

Are you *sure* that the filesystem isn't full?  
Can you show df(1) output?
