   Thanks, @cbalci for drafting this message.
   We have faced this issue 2 times since last month 
   For the first instance of the issue I made the debugging a couple of weeks back, these are the series of events which triggered the undesirable state of segments ( I got this from the log dump ) 
   
   **Setup** 
   
   - Contoller ( C )
   - Server - S1 , S2  - Both consuming same segment ( X ) from Kafka 
    
    Series of Events in Incresing order of Time 
   | Time | C | S1 | S2 |
   |--------|--------|--------|--------|
   | T1 | Segment X has started consuming | - | - |
   | T2 | Comittting Segment X with Winner S1 | - | - |
   | T3 | Cell | Segment Tar built | Cell |
   | T4 | Cell | Failure to Upload To DeepStore | Cell |
   | T5 | Updated Segment Metadata And Idealstates are set for this segment | Cell | Cell | 
   | T5 | Updated Segment Metadata And Idealstates are set for this segment | Cell | Cell |
