   应该不会是这里的问题，可以观察下是不是一直打印load schema from service center......相关日志

   上游服务A长时间不重启，下游服务B频繁变更升级，导致A不停加载B服务契约，导致内存消耗增加。

   Following up on the memory-growth report on 2.8.24.

   #5062 (against 2.8.x) and #5064 (against 2.9.x) were opened for this issue, then closed on 6 March 2026 without being merged, and their head branches were deleted. I compared SwaggerLoader.java in 2.8.24 with the later published 2.8.31 and 2.9.5 releases; the file content is the same, so I do not see this change in a published release.

   On #5064 there was also an open question about whether the proposed cache-key change would actually address leaks caused by frequent version upgrades. I have not verified a root cause or a working fix.

   Could you confirm whether you can still reproduce this on a later published 2.8.x or 2.9.x release, and share sanitized memory / load schema from service center observations if you can? That will help us decide the next investigation step.
