Never had no problem with it.
The only problem I've hit was due to the binding file being, by
default, located in /var/lib/multipath, which is in my setup on a
separate LV than /, during boot time the devices were not correctly
Just had to switch the binding file to /etc and now no more problem.
extract of my /etc/multipath.conf :
