я имею в виду вот этот код

+ if (n == -1) {
+ err = ngx_errno;
+
+ switch (err) {
+ case NGX_EAGAIN:
+ ngx_log_debug0(NGX_LOG_DEBUG_EVENT, c->log, err,
+ "sendmmsg() not ready");
+
+ ngx_quic_revert_send(c, ctx, preserved_pnum);
+
+ ngx_add_timer(&qc->push, NGX_QUIC_SOCKET_RETRY_DELAY);
+ return NGX_OK;
+
+ case NGX_EINTR:
+ ngx_log_debug0(NGX_LOG_DEBUG_EVENT, c->log, err,
+ "sendmmsg() was interrupted");
+ goto eintr;
+
+ default:
+ c->write->error = 1;
+ ngx_connection_error(c, err, "sendmsg() failed");
+ return NGX_ERROR;
+ }
+ }

ну то есть искать либо "sendmmsg()", либо явно поправить ngx_log_debug,
чтобы удобнее было искать

в том, что вы прислали, я не вижу такого патерна
