Vim started crashing on me, particularly when I tried to open new

I rebooted my machine (which has been super-solid for years) - and
the difference was gone.

So, what are the opinions - did I run into a hardware glich, or was
there a freaky issue with memory mapping?
I think I'd run 'badblocks' on the disk.
Or turn swap off and remake it with -c?

Remake what with -c? I don't see a -c option with swapon().
I said reMAKE, not turn it on again
mkswap
-c Check the device (if it is a block device) for bad blocks before
creating the swap area. If any are found, the count is printed.


Oh, you mean the swap partition?

Hmmm. You mean you think executable images get swapped out?


I do not know (surely someone does) if inactive code gets paged out or not,
but the associated data surely can. And it may be faster to page inactive
code to swap space and back (where the information is likely to be
contiguous) rather than to a file system file (of course you would not have
to write it) and back.
