Suction line insulation deteriorating

First time poster and I would like to get an opinion on what could cause this. The suction line insulation before the compressor is deteriorating at a rather rapid pace. There is a large wet spot under it on the concrete. The foam is soaked. Smells like water but not sure if gas is leaking out. Not sure what could cause it.

I realize sweating is normal, but the unit next to it isn't sweating and the foam seems to be falling apart it's so wet.

Likely getting a little more air and moisture in and sweating more. If a Freon leak there might be oil or feel oily.

As the foam gets older it hardens and crumbles. It just needs to be replaced.

It feels a little slick. No smell. I'm wondering if the deterioration of the foam is making it slick. Thanks for the replies. I'm only worried because that other unit looks to be in better condition and they are a little over 3 years.

The black foam has oil in it from the production process. It could be separating out.

If the foam is not sealed all the way back to the conditioned area... it will sweat inside and run to the lowest point which is right there at the condensor.
