I'm pretty I encountered the same leak over here, 15 days uptime and I had consistent out of memory problems, I got angry and did go in single user mode and noticed that with only systemd->screen->bash(2) I had 2 GB of memory used on 4 GB total. This box mostly has random reads and just before the out of memory condition had 12 GB written to a lot of files.
