Hi, Andrew!

I doubt it's the same problem, but there's another thread where
rebooting helps:

Re monitoring in aggregate, I know there are people here way more
knowledgeable than me, but if you haven't been able to make any progress
on tracking this down, I wonder if periodically capturing the output of

  vmstat -CmW

and

  netstat -m

might help on the outside chance that they might show some statistic
change over time that could lead you to the source of the problem?
