eapolclient process using 30GB of memory?
You have at least three processes running wild:

eapolclient:       probably related to 802.1x protected networks
CCXProcess:   related to Adobe Creative Cloud
CCXLibrary:     related to Adobe Creative Cloud  

The last two obviously occur after the update to Creative Cloud 3.4.0.180. A staff member of the Adobe forum advises to update to Creative Cloud 3.4.0.181.

To solve your problem for now try to quit or kill the three processes in Activity Monitor. Then try to quit all other running apps graciously (by quitting them from their menubar), restart the machine and check if it's still the same.



There is some evidence that the Creative Cloud problems are related to corrupted preferences files. You may try to create a dummy user, log-in with your CC credentials and check if the problem persists.
