[sysvinit-devel] sysvinit causing many reads?

[Ortwin Glück]

Hi,

Browsing I/O statistics taken by atop on a DB server I came across this curious 10 minute slot where 
init was apparently causing enormous reads on the system:

  PID              TID              RDDSK             WRDSK             WCANCL              DSK 
       CMD        1/72
    1                -               3.3G              428K                 0K              63% 
       init

Also it is the top source of I/O since boot 76 days ago:
  PID              TID              RDDSK             WRDSK             WCANCL              DSK 
       CMD        1/19
    1                -               3.8T              2.1T               1.9G              66% 
       init
30892                -               1.4T              3.1G             139.9M              15% 
      cron
 2672                -              57.2G              1.0T                 0K              12% 
       oracle

I wonder how that is possible and if it is a bug.

The system is Gentoo with sysvinit-2.93 on linux-4.20.17.
