[GitHub] [pulsar] KannarFr commented on pull request #17254: [fix][broker] Fix intermittent issue where leader broker information is lost and causes lookup issues

KannarFr commented on PR #17254:
URL: https://github.com/apache/pulsar/pull/17254#issuecomment-1232850099

   To be sure, could this issue result in 502 during topic creation? I just had this problem.
   
   I had these logs on brokers:

   ```
   
   Then nothing related to this customtopic even on another broker. And the response was HTTP 502.
