/run is mounted during early boot by PID 1 itself, and its size
defaults to 50% of the available system memory.

You can remount the file system any time you like to adjust its size limit:

    mount /run -oremount,size=...

You can add a line for this to /etc/fstab actually. If it is listed
there then systemd will automatically remount /run during late boot
with the parameters listed in there, through 
systemd-remount-fs.service.
