We are seeing a fatal assertion error on a couple of our servers. The error has happened a few times in the past week. After the first error we resynced the data on one of the replicas (in case it was a result of corruption) but it reoccurred after a couple days.
We are running version 3.2.8 with the MMAPv1 storage engine.
The backtrace is below, let me know if there is any additional information I can provide.
