You can have a lot more exposure. I make no where near your income. My highest chase card is over 30k and I have several chase cards.
I've got two cards with Chase, one at $26.5k and one at $25k, so you are nowhere near maxed out for CL with Chase given your income, assuming all other factors are positive (ie: clean report with decent history/AAoA). I am sure there are others with far more exposure with Chase, and FWIW when I went into a branch to inquire about opening a checking account with them, I was assure I was pre-approved for Slate if I wanted it (which I passed on).
I was just calling to ask them to expidite my Ink card like they did the SW and instead of going to a CSR it went to a different department from there I spent 15 mins verifying my birthplace, what state my social is from and she told me "your accounts are being reviewed, that's all I can tell you"
Ouch! Hopefully everything will work out ok. I'm going to assume it was probably the Ink card that caused the review of all your accounts. What does your credit profile look like? How many new accounts in the last year? How many Chase cards?
Yikes, I guess this is why people say never call chase if you don't absolutely have to and if transferred to lending hang up. Well I don't know how long it takes but good luck, hope you make it out unscathed.
I'm going to assume that when Chase does these reviews they are looking over all accounts with a fine tooth comb for things like questionable spending (ms), bonus chasing, excessive new accounts, anyone else at your address doing the same, etc. That's just my guess though.
