      Description

      Build 6.5.0-4926

      Observed following panic while running performance test experiments suggested by Varun Velamuri to understand incremental build timings.

      In this experiment we have 1B docs, create 4 indexes on fields of ~128 byte length and then do incremental builds. This panic observed while building first index. We used plasma storage and supposed to go ~20% RR.

            Closing this as this panic is not seen in any recent CC builds.
