searching the net I found bug reports of the notification-daemon failing that included tests like this:

$ notify-send 'Hello world!' 'This is an example notification.' --icon=dialog-information

when I ran this test I got a popup window showing the text.
This popup window looked exactly like the popup window I get when I use the firefox extension 'Empty Cache Button'.

I did some hitting of the cache button which caused time matching log entries.

So, afaict, the hitting of 'Empty Cache Button' is the likely cause of the following logs entries.



looking at /var/log/messages I'm seeing these:

there are no log messages that indicate a possible relationship between these and some other event (i.e., usb).

I went through compressed logs for the prior 7 days and found no other events like these.
That last item is the last item in the current /var/log/messages file.

system has been up for 60 days

# uname -a
Linux localhost 3.16.5-gentoo #3 SMP Wed Nov 26 03:54:40 PST 2014 x86_64 Intel(R) Core(TM) i7-4820K CPU @ 3.70GHz GenuineIntel GNU/Linux

Any ideas?

Thanks
