    Description

      Build : 5.5.0-2958 (RC4)

      While the system was running, a query was run separately on the same cluster (query is not a part of the test). This query resulted in a panic on the query log. Upon retrying the query, it returned results and didnt result in an error. Re-ran twice again, it panic'd once more. So 2/4 times it panicked.

      Query
      select meta().xattrs._sync.sequence
      from default
      where meta().xattrs._sync.sequence is not null
      limit 10

            Description Build : 5.5.0-2958 (RC4)

            While the system was running, a query was run separately on the same cluster (query is not a part of the test). This query resulted in a panic on the query log. Upon retrying the query, it returned results and didnt result in an error. Re-ran twice again, it panic'd once more. So 2/4 times it panicked.
