Not necessarily anything wrong, other than the two machines are not identical.
/run/user/xxx is used by session management (and in some corner cases its
absence can break dpkg scripts).
You could list all the processes on both machines and then diff them.
Quick and dirty (and untested :)
local_host# ps -e | awk '{print $4}' | sort | uniq >/tmp/catch0
local_host# ssh remote_machine 'ps -e' | awk '{print $4}' | sort | uniq
>/tmp/catch1
local_host# diff /tmp/catch0 /tmp/catch1
