I'm having the same issue since re-subbing a couple of days ago. It's seems to be fairly random, but always and only with CoX. It happened a few times in a row last night on my MM while trying to summon and equip all of my bots...not sure if that's significant or not. The only changes I can think of from the last time I played are that I've moved to a new apartment and any updates to CoX in the past six or so months. I was leaning toward the former, but after happening upon this post, and the fact that it only occurs while running CoX, I've reconsidered. Please tell me someone figured this one out.
