Something I have noted on the AI's part at times: It gets into a war and expends all it's effort on it's opponent ignoring neutrals on another side.

Now, if it got into a war with someone on land that it couldn't attack it could get stuck.

I'm in a game against the AI now where I saw that with two empires. They both declared war on me and completely ignored a whole pile of neutrals. In one case I had deliberately left some of those neutrals alone so the AI would have an expansion path that didn't go through me as I didn't want to force a war while I was still expanding. It took the AI a few years to go around the mountain through the neutrals. (My army was mostly involved against the other AI and I was simply holding a chokepoint against the guy.)
