panic possible on sending from closed channel during high-volume readstream

[edaniszewski]

This was captured in the backgrorund, so there isn't much context around what exactly was running at the time, the throughput, etc, but looks like when there was A LOT of data streaming through, this happened once:

time="2021-01-11T01:15:28.596Z" level=info msg="closing read stream" id=1bc95670-c4a3-4b8a-94fc-28225fa67782
panic: send on closed channel

goroutine 425 [running]:

will need additional investigation and RCA
