[I] [multistage] Mailbox Errs Without Logs on Inbound Message Limit Breach [pinot]

ankitsultana opened a new issue, #15741:
URL: https://github.com/apache/pinot/issues/15741

   We were seeing an issue where queries would fail with "Client cancelled" on the receiver side, and "RST_STREAM" error on the sender side. Outside of this, there were no logs to indicate what the issue was.
   
   Enabling gRPC Debug logs showed that the issue was `errorCode=8`, which refers to resource exhaustion: https://grpc.github.io/grpc/core/md_doc_statuscodes.html
   
   After increasing the buffer limit the queries work fine.
   
   ```
   {"@timestamp":"2025-05-08T02:47:38.502+00:00","@version":1,"message":"[id: 0x047e448d, L:/10.148.247.202:44029 - R:/10.148.33.163:32918] OUTBOUND RST_STREAM: streamId=15 errorCode=8","logger_name":"io.grpc.netty.shaded.io.grpc.netty.NettyServerHandler","thread_name":"grpc-default-worker-ELG-3-1","level":"DEBUG","level_value":10000,"HOSTNAME":"some-hostname"}
   ```
   
   As part of this ticket we should improve logging for this scenario.
   
   This is kinda unexpected because in the past I have seen "RESOURCE_EXHAUSTED" errors when gRPC message size limits are breached, but maybe BiDir calls are not handled gracefully by gRPC?

   @shauryachats : can you confirm if your patch has fixed this issue?
   
   As in, before your patch, queries with this error would fail silently and block till timeout.
   
   After your patch, queries should fail fast and return a proper error message to users.
