When displaying the current memory usage on Juniper MX systems (running JunOS 21.4, in case it should matter), I do see an entry for
Laundry. For example:
> show system processes extensive
Mem: 13330M Active, 430M Inact, 13918M Laundry, 3198M Wired, 1374M Buf, 904M Free
Other Juniper systems like the EX and QFX switches do not show this field under
show system processes extensive. Junipers own documentation for memory management also does not mention
Laundry anywhere, although it explains all the other fields in detail.
What is this "Laundry"-memory, and is it safe to assume it can be released by the system if required for something else? (Or is the above system close to running out of memory?)
