[HTCondor-users] No ProportionalSetSizeKb in Job ClassAd

[Todd L Miller <tlmiller@xxxxxxxxxxx>]

I can't find the 'ProportionalSetSizeKdb' in Job ClassAds even though
USE_PSS is set to True.  I tried to find a clue for it but failed. 
Could you please let me know where to look for the clue, or why it isn't
there?

FYI, I have 2 queues (which configured by others) which runs

  * v9.0.11 on SL7.9
  * v23.9.6 on RHEL9.4

and PSS is not on both queues.

I'm not sure if it is helpful for diagnosing but here is an excerpt from
'ProcLog'

The 'smaps' files are under '/proc' dir (but not the ones in the logs)
and there are Pss info there so I think PSS is supported by OS.

As a simple user without knowing much about configuration, it is hard to
understand the logs.  My naive guess is that the processes might have
been disappeared before 'getPSSInfo()' is being called or something.

Thank you and kind regards,
