      Description

      After the mongodb server suddenly loses power, it restarts with the Got signal: 6 (Aborted).

      The mongodb engineer helped me fix the WiredTiger.wt and WiredTiger.turtle files, but the problem still exists.

      What else can I do to save my data? Thank goodness.

      Most recent stacktrace is here:
