Lots of things use shared memory. All you know here is that something
is
using lots of it
You haven't done much useful to track it down. Find the process that
is
really using memory. A very quick easy first step is to run top and
sort
on the memory columns (just take the left-most memory-related column
with a big bag of salt, it doesn't show what people usually think).
Then
correlate that with packages you recently updated.
Thanks Alan.
I think my problem is a bit more complicated.
I did try to identify a process which eats my memory, but I couldn't
find one.
I have written a small Python program which does something similar to
htop / atop
which I've used before.
And here is what I get (I have summed up all 'visible' memory that top
would have shown)
And please, compare this to what I see as memory usage.
