It's this message:
The easiest / most basic information to get is just the stack trace from
the daemon that is supposed to be trimming the cache back when it gets
full. That message contains the commands where you can get that
information via the 'crash' tool.
Or, another way to get that information is by running this:
# echo t > /proc/sysrq-trigger
That will generate a ton of information to the kernel log, which you'd
need to sift through or give to someone else. But it's at least a lot
easier to set up and run.
