According to the above two posts, either we ignore the errors by editing the rsyslog configuration, or change the snmpd log level.

If they are unrelated and should never be caught they should be added to the ignore list files.
if they are not related to specific test the relevant test ignore file should be updated.

Please review the common ignore files and update it if needed.

the root cause is those directories are not available after we do aufs. @qiluo-msft, is there any way to not show the /root/dev, /root/dev/pts, /root/host in the /proc/mounts?

admin@str-s6000-acs-7:/var/log$ sudo grep root /proc/mounts
rootfs / rootfs rw 0 0
udev /root/dev devtmpfs rw,relatime,size=10240k,nr_inodes=1020200,mode=755 0 0
devpts /root/dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0
/dev/sda3 /root/host ext4 rw,relatime,data=ordered 0 0
/dev/loop0 /root squashfs ro,relatime 0 0

Reopen this. But low priority.
