Gary-Airwallex opened a new issue #2938:
URL: https://github.com/apache/apisix/issues/2938


   ### Issue description
   We have the prometheus plugin enabled in global rule and query the /apisix/promethues/metrics endpoint once per second. After upgrading to APISIX 2.0 from 1.5, occasionally we see ERROR logs like this: 
   `[error] 36#36: *105103628 [lua] http.lua:951: request_uri(): unread data in buffer, client:, server: , request: "GET /apisix/prometheus/metrics HTTP/1.1"`
   
   ### Environment
   
   * apisix version (cmd: `apisix version`): 2.0
   * OS: linux
   
   ### Minimal test code / Steps to reproduce the issue
   1. We weren't able to reproduce this issue. 
   
   ### What's the actual result? (including assertion message & call stack if applicable)
   Errors, see above. Not sure if this has any impact on the prometheus metrics?
   
   
   ### What's the expected result?
   No errors.

   Strange. We just tweak some metrics between 1.5 and 2.0, which should not affect the way to fetch the data. Need a packet capture file and corresponding error log to confirm it.
