I am running 10.14.6 (18G3020) on a 2018 MacBook Air.

Every 15 seconds or so a triplet of files is created in /private/var/db/powerlog/Library/BatteryLife/Quarantine. For example

30144 -rw-r--r--  1 root  wheel    15M Apr  1 17:02 CorruptPowerlog_1585785775.350699.PLSQL
   64 -rw-r--r--  1 root  wheel    32K Apr  1 17:02 CorruptPowerlog_1585785775.350699.PLSQL-shm
    0 -rw-r--r--  1 root  wheel     0B Apr  1 17:02 CorruptPowerlog_1585785775.350699.PLSQL-wal

This means that my disk space is shrinking by 60MB per minute.

I can delete these files as root, but they keep coming back.

What program creates these files? How can I stop this?

  • Try booting into safe mode, and back into normal – anki Apr 2 at 6:38
  • @ankii Thank you for your comment. The issue persists after implementing your suggestion. In fact, the issue persists during safe mode. – robust Apr 3 at 19:03
  • Are you using some app or diagnostic tool or battery life logger? – anki Apr 6 at 8:25
  • @ankii not that I know of. I also presume that such a tool would be disabled during safe mode. – robust Apr 6 at 22:20
