Oh sure, sorry for the confusion! So the 10th request could successfully grab a DB connection from the pool, it’s actually the last connection in the pool. Then when the 11th request came in - assuming all first 10 requests are awaiting on some asynchronous tasks (keeping 1 DB connectionn each!) - it will firstly try to acquire a new connection, but there isn’t any more to spare, so it blocks, and it’s blocking the thread. It’s like an infinite loop that keeps acquiring connections from the pool but never returns, it will block forever and won’t get unblocked just by itself.

What is the general attitude to English in IT in China? is this something optional? why am I asking - in Russia there are always disputes about whether it is necessary to localize documentation or projects? it is believed that this stimulates the isolation of development within the country, while English, on the contrary, allows you to expand the scope

Oh yeah sure - I think the default option for open source projects is English, this applies in China too, where I believe most people are starting their projects in English, or at least think English is kinda mandatory if they want to expand the scope like you said. And I truly beliebe people like to share, in my country too. I do see some projects started with Chinese only, but they are also being used on WeChat only and the target users are also mostly Chinese. But these are rare cases.

Thanks @fantixking ! That was very interesting! 🚀
