This is probably not caused directly by the reverse proxy. For API-created posts, Discourse uses DistributedMemoizer around PostsController#create to avoid duplicate API post creation. That memoizer uses a Redis-backed DistributedMutex with a very short validity time of 1 second. The warning means that the post creation / serialization work inside that lock took longer than expected. So: if the API post is still created successfully, this is a warning rather than the root failure; expected max: 1 secs, took an extra 1 secs means the lock was held for roughly 2 seconds; it is more likely related to server performance, Redis/Postgres latency, disk I/O, CPU/RAM pressure, plugins, or slow post-processing than to nginx/1Panel reverse proxy itself; the reason it only appears for API posting is that this memoizer path is used for API requests. Things worth checking: Does the API request succeed and create only one post? How long does the API request take from the client side? Are CPU, memory, swap, or disk I/O saturated during API posting? Are Redis and Postgres inside the same container/host, and are they healthy? Does the warning still happen with a very small plain-text post and no images/uploads? Are there non-standard plugins installed? Since this is a 1Panel/container deployment rather than the standard Discourse Docker install, it may also be useful to reproduce on an official supported install if possible before treating it as a Discourse core bug.

谢谢您的回复。我这个网站主要用于个人知识管理使用，没有开放注册，只有我一人在线。vps性能是10 vCore (ARM64)，16 GB RAM，512 GB NVMe。我觉得性能上应该没问题了。 1、API 请求是否成功，并且只创建了一个帖子？是的，API发帖成功，并且只创建一个帖子。 2、从客户端角度看，API 请求耗时多久？这个应该怎么查询？我不太了解。 3、在 API 发帖期间，CPU、内存、交换空间或磁盘 I/O 是否已饱和？我查看了一下监控记录，API发帖时，以上资源使用未饱和 4、Redis 和 Postgres 是否位于同一容器/主机内，且运行正常？是在同一容器内，并且运行正常 5、如果发布的是纯文本小帖子且没有图片或上传内容，警告是否仍然出现？纯文本小帖子也出现警告 6、是否安装了非标准插件？除了官方默认安装的插件，其他插件均未安装

刚才我把ai插件关掉，通过api发帖，日志中没有出现警告。再开启ai插件，重新通过api发帖，日志中也没有出现警告。我再观察测试一下。

Thanks, that extra detail is useful. Since you are running on ARM64, that may be relevant. Discourse’s ARM/aarch64 container support has historically had some special handling compared with x86_64, so I would mention that clearly in the topic title or first post. The AI plugin result is also interesting. Since the warning disappeared after disabling the AI plugin, but did not immediately return after re-enabling it, this might have been caused by some one-time initialisation, cache warm-up, model/provider setup, or background state rather than a consistent reproducible plugin bug. At this point I would keep observing, but if it happens again I would try to capture: the exact API endpoint and payload shape, with any private content removed; whether the warning appears on the first API post after restart/rebuild only, or every API post; the client-side request duration; whether disabling the AI plugin reliably removes the warning across multiple tests; whether the same happens on x86_64 or only ARM64, if you are able to test that. For checking client-side request duration, you can use curl with timing output, for example: curl -s -o /dev/null \ -w "total=%{time_total}s connect=%{time_connect}s starttransfer=%{time_starttransfer}s\n" \ -X POST "https://your-site.example.com/posts.json" \ -H "Api-Key: YOUR_API_KEY" \ -H "Api-Username: YOUR_USERNAME" \ --data-urlencode "title=API timing test" \ --data-urlencode "raw=Small plain text API test post" \ --data-urlencode "category=1" If the request itself is taking around 2 seconds or more, then the mutex warning is probably just reporting that the post-create path took longer than Discourse expected. If the request is very fast but the warning still appears, that would be more interesting. The hardware looks more than sufficient for a single-user site, so this may be architecture/deployment/plugin-path specific rather than simple under-provisioning.

我关闭一段时间 discourse ai 看看是否还出现这个警告

目前测试来看，警告日志的出现与是否启用了discourse ai无关

Thanks for testing that. In that case I would not treat the AI plugin as the likely cause. It may just have been a coincidence, or the disable/re-enable cycle may have changed some transient state temporarily. The most useful next thing to capture is probably the request timing and the pattern of when the warning appears. For example: curl -s -o /dev/null \ -w "total=%{time_total}s connect=%{time_connect}s starttransfer=%{time_starttransfer}s\n" \ -X POST "https://your-site.example.com/posts.json" \ -H "Api-Key: YOUR_API_KEY" \ -H "Api-Username: YOUR_USERNAME" \ --data-urlencode "title=API timing test" \ --data-urlencode "raw=Small plain text API test post" \ --data-urlencode "category=1" If the warning appears again, it would be useful to compare: the time_total value from the client side; whether it happens only sometimes or on every API post; whether it happens after a restart/rebuild, or during normal running; whether multiple API requests are being made close together; whether the same API call creates the post successfully and only once. At this point it still sounds like a warning from the API post-create path taking longer than the short mutex window, rather than evidence of a failed post or duplicate-post problem.
