Yes, 400MB swap, only a small fraction of it used; vmstat 5 looks okay
and shows no understandable reason for the error message. Here are a
few lines from vmstat: the point at which free memory jumps up is just
after the "Write failed: Cannot allocate memory" message:

I have many hundreds of MB or GB of disk space in the various
partititions. I will try the newer kernel, though I am interested in
understanding what's going on here too.
