HI,
I have sever app (golang) which provides streaming connection to client.
I'm running few clients which make grpc stream connection with server. I
continuously
restart client by doing kill.After 30 minutes, on server I see memory is
leaked by transport.newBufWrite
<http://google.golang.org/grpc/internal/transport.newBufWriter> Has the
pporf output.
Has anybody seen such issue ?
