sudo：PERM_ROOT：setresuid（0，-1，-1）：不允许操作

Question

So the problem is that the error comes up in apache.err.

I CAN execute as the user in the shell.

root@ubuntu:~# su www-data
www-data@ubuntu:/root$ sudo /usr/local/bin/metronomectl restart
Stopped
Started
www-data@ubuntu:/root$

but when i try the same command through php

exec('sudo /usr/local/bin/metronomectl restart');

i get the error

sudo: PERM_ROOT: setresuid(0, -1, -1): Operation not permitted

user www-data IS in sudoers.

I'm at the end of my wits here... Any help is appreciated.

PS. Please ask if you need any extra info.

edit:

Fixed by disabling mpm_itk module in apache.
