           Summary: plasma_session memory leak
           Product: kde

SUMMARY
I've noticed that my system seems to suffer giant memory leaks over time,
coming from process plasma_session. Researching told me that various people
experience this from process plasmashell, but it doesn't seem to be my case as
it's sitting on about 670mb compared to the current 15gb from plasma_session.
Rebooting fixes it but eventually it'll come back.
I don't turn it off overnight (I have my reasons for it) and when I turn the
monitors back on I'm usually welcomed with a series of notifications that say
kde has crashed? I don't know if that has relevance on the issue.

I couldn't tell when this started but it's relatively recent as I can't say
I've seen this happen last month or so. I tried looking in the kde bug tracker
but I'm not experienced with this stuff just yet so I didn't find anything
related to plasma_session memory leaks.
It just keeps increasing and I don't know what to do.
I made a post on reddit which suggested filing a bug report, so here I am

OBSERVED RESULT
Memory usage way too high, growing over 10, 12, 14gb and counting

EXPECTED RESULT
Definitely not >10gb of plasma_session
