Yes I have seen the same thing. I have some liquid and paste flux so, if I
am using the old stuff, I paint the joint where I am soldering before I
apply the solder.
I had a joint outside that has been exposed to weather the past 4+ years
that needed to be soldered. By using the flux the joint took the solder on
the first pass.
I vaguely recall someone telling me that
the rosin flux in the core deteriorates with age, something I took with a
grain of salt, but maybe they were correct.
