  "message": "HTTP/2: fixed closed_nodes overflow (ticket #1708).\n\nWith large http2_max_concurrent_streams or http2_max_concurrent_pushes, more\nthan 255 ngx_http_v2_node_t structures might be allocated, eventually leading\nto h2c-\u003eclosed_nodes overflow when closing corresponding streams.  This will\nin turn result in additional allocations in ngx_http_v2_get_node_by_id().\n\nWhile mostly harmless, it can result in excessive memory usage by a HTTP/2\nconnection, notably in configurations with many keepalive_requests allowed.\nFix is to use ngx_uint_t for h2c-\u003eclosed_nodes instead of unsigned:8.\n",
