      Hi,
      I've a problem with mongodb. I wasn't able to start it.

      ***aborting after fassert() failure
      

      I tried to install WiredTiger tool on my mac and use the Salvage command but it still logs the same error.
      Could you please help to recover my database, it's very important.
