Limit to number of concurrent websockets for go-ipfs?

Was curious if there was any sort of specific limit for the number of go-ipfs websockets supported? I am using nginx as a websocket proxy and have left the proxy_read_timeout to the default 60 seconds but every once in a while, the bootstrapped connection from js-ipfs to go-ipfs over wss hangs and requires an ipfs daemon restart as well as an nginx restart.

I was thinking this may be due to connections being left open and accumulating to the point of depletion.
