A hundred /Volumes/OS X Base System Mounts?

So I was in Terminal Today (I'm a Unix system admin, I know what I'm doing) and happened to run a "DF".

Apparently I have literally 100 copies of "OS X Base System" Mounted into my /Volumes area on my Mac.

What gives? Why would I have 100 copies of "OS X Base System" Mounted?

A Snippit from DF:

1.2Gi
712Mi 63% 44914 4294922365 0%

Can anyone explain to me what the **** is going on? Are these all Unmountable without problems? Why do I have literally 100 copies of the base OS mounted?

MacBook Pro, macOS High Sierra (10.13.3)

Hello Illydth,

Double-check your login items to make sure you aren't launching the macOS installer or something.

If you are a sysadmin, you might be doing some sysadmin tasks that could leave these things left behind. I have noticed a bug recently where macOS will keep old disk image devices around. Do you actually have those images currently mounted? If not, then it is probably that bug. Just restart your system. As macOS loses reliability, regular restarts are more and more necessary.

Thanks for the reply, these were actually mounted images of the OS X Base Image apparently. When I went into disk utility all 100 of them were showing up on my side bar and clicking the "eject" button did, indeed, eject each one.

Now I'll have to pay attention to various things to see if they start coming back (reboots being one, etc.) seems quite excessive for anything to have mounted 100 Copies of the base image, but *shrug*.

Thanks for the response!
