When I checked my logfiles on the primary server I noticed errors that my 3rd server in the 3 server cluster could not be reached. When checking on the server I found mongod was not running, so I tried to restart the service and got a 34433 fatal assertion.
This server is running as an arbiter only, so I am a bit surprised to see this WiredTiger error on this machine.
The output of /var/log/mongodb/mongod.log:

Running 'mongod --dbpath /var/lib/mongodb --repair' resulted in an aborted repair, but after restarting the mongo service the fatal assertion changed to 28578.

***aborting after fassert() failure
After removing the '/tmp/mongodb-27017.sock' file and chowning all files in '/var/lib/mongodb' to 'mongodb:mongodb' I am back to 34433 error when restarting the service. I did edit the logfile output and removed only my external IP address.
