Is there any max limit of a mempool?

I mean 32mb/64mb/128mb beyond which it will crash or wont relay new Tx or remove old Tx to accept new one. If there is no such fixed size, I'd like to know the max limit of an average node...

Bitcoin Core has a default max mempool of 300 MB, after which point it will start kicking transactions and increasing the minimum fee to get accepted.

I think it happens in this function: https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L527

In case you want to change that behaviour you dont have to modify the source. You can use the maxmempool setting (either pass at start or via .conf file).
