Cleaning old PHP session files doesn't work

[azurit]

Cleaning old PHP session files using systemd service/timer phpsessionclean doesn't work:

Sep 4 21:32:01 cloud0001 systemd[1]: Starting Clean php session files...
Sep 4 21:32:01 cloud0001 systemd[31959]: Failed at step NETWORK spawning /usr/lib/php/sessionclean: Invalid argument
Sep 4 21:32:01 cloud0001 systemd[1]: phpsessionclean.service: main process exited, code=exited, status=225/NETWORK
Sep 4 21:32:01 cloud0001 systemd[1]: Failed to start Clean php session files.
Sep 4 21:32:01 cloud0001 systemd[1]: Unit phpsessionclean.service entered failed state.

Everything starts to work fine after removing this line from systemd unit file:
PrivateNetwork=true

Debian Jessie, 64bit, using original Debian kernel and systemd.

Thank you!

Should be fixed since php-defaults/55.

hey @oerdnj ! I cant find php-defaults/55 in any debian suites, and this error occurs also on stretch - any plan to upload the fix to stable-updates?

I've seen this issue as well, and cherry-picking the patch indeed makes it go away. +1 for stretch-proposed-updates.

Oh, my bad. I'm seeing the similar but different CGROUP issue:
