// Issue #23116
|
|
// nghttp2 keeps closed stream structures around in memory (couple of hundred
|
|
// bytes each) until a session is closed. It does this to maintain the priority
|
|
// tree. However, it limits the number of requests that can be made in a
|
|
// session before our memory tracking (correctly) kicks in.
|
|
// The fix is to tell nghttp2 to forget about closed streams. We don't make use
|
|
// of priority anyway.
|
|
// Without the fix, this test fails at ~40k requests with an exception:
|
|
// Error [ERR_HTTP2_STREAM_ERROR]: Stream closed with error code
|
|
// NGHTTP2_ENHANCE_YOUR_CALM
