    Description

      Running an automated restore from a MDB 4.2.6-ent / FCV 4.2 replica set WT checkpoint snapshot into a MDB 4.4.0-rc5-ent / FCV 4.4 replica set.

      During this step in the automated restore process, we get an fassert trying to start up the 4.4.0-rc5-ent non-arbiter process as a standalone:

      {"t":{"$date":"2020-05-10T23:13:33.648+00:00"},"s":"W",  "c":"STORAGE",  "id":22347,   "ctx":"initandlisten","msg":"Failed to start up WiredTiger under any compatibility version. This may be due to an unsupported upgrade or downgrade."}
      {"t":{"$date":"2020-05-10T23:13:33.648+00:00"},"s":"F",  "c":"-",        "id":23089,   "ctx":"initandlisten","msg":"Fatal assertion","attr":{"msgid":28559,"file":"src/mongo/db/storage/wiredtiger/wiredtiger_util.cpp","line":64}}
      {"t":{"$date":"2020-05-10T23:13:33.648+00:00"},"s":"F",  "c":"-",        "id":23090,   "ctx":"initandlisten","msg":"\n\n***aborting after fassert() failure\n\n"}
      {"t":{"$date":"2020-05-10T23:13:33.648+00:00"},"s":"F",  "c":"CONTROL",  "id":4757800, "ctx":"initandlisten","msg":"{message}","attr":{"message":"Got signal: 6 (Aborted).\n"}}
      

      Note – this did not happen with the same test on 4.4.0-rc3 or rc4.

      Found this in an automated test – attaching a potentially excessive amount of mongo logs here in case you need the historical logs.
