CRON pgrep "ftpd|nfsiod|smbd|afpd|cnid constantly called

[Gord_W]

Using V6.4 on Nanopi Neo with only Netdata running headless with openssh.

journalctl shows CRON job gets repeatedly called once every minute. I don't believe this does anything for me ... is the intended?

Was wondering if this is a bug? What can I do about it?

Hi Gordon,

Many thanks for the report.

Please can you paste results of:

Code: Select all

cat /etc/crontab

Ticket created:
https://github.com/Fourdee/DietPi/issues/1654

[Gord_W]

root@DietPi:~# cat /etc/crontab
#Please use dietpi-cron to change cron start times
SHELL=/bin/sh

Okay, crontab looks as it should, new cron.minutely is not the reason, as it is set to every 30 minute and the journal output looks different.

Other two possibilities, root user crontab and cron.d. Could you please provide result of:

Code: Select all

ls -l /etc/cron.d
sudo crontab -l

[Gord_W]

root@DietPi:~# ls -l /etc/cron.d
total 8
-rw------- 1 root root 106 May 24 2017 make_nas_processes_faster
-rw-r--r-- 1 root root 123 May 24 2017 openmediavault-rrdtoolgraph
root@DietPi:~#


root@DietPi:~# sudo crontab -l
no crontab for root
root@DietPi:~#

[Gord_W]

root@DietPi:~# cat /etc/cron.d/make_nas_processes_faster
* * * * * root for i in `pgrep "ftpd|nfsiod|smbd|afpd|cnid"` ; do ionice -c1 -p $i ; done >/dev/null 2>&1
root@DietPi:~#

That seems to be the offending line.

[MichaIng]

Seems to be part of Rock64 base image: https://github.com/ayufan-rock64/linux- ... ses_faster

But I don't get it, shouldn't it be working to just call this once after boot e.g.? Totally spammy like this, and most users do not even use any of these services :evil:.

So just remove that file or do:

Code: Select all

mv /etc/cron.d/make_nas_processes_faster /etc/cron.d/.make_nas_processes_faster 

to let it be ignored by cron.

[Gord_W]

what about openmediavault-rrdtoolgraph ?
That doesn't seem to be needed either??

make_nas_processes_faster
openmediavault-rrdtoolgraph

By deleting those two files there are less entries in journalctl output.

thanks,
