[QUESTION] Object synchronization method was called from an unsynchronized block of code

See original GitHub issue

I’m getting this error intermittently while running with ConnectionType.Shared and don’t with the default.

System.ApplicationException: Object synchronization method was called from an unsynchronized block of code.

   at System.Threading.Mutex.ReleaseMutex()
   at LiteDB.SharedEngine.CloseDatabase()
   at LiteDB.SharedEngine.Upsert(String collection, IEnumerable`1 docs, BsonAutoId autoId)

System.ApplicationException: Object synchronization method was called from an unsynchronized block of code.
   at System.Threading.Mutex.ReleaseMutex()
   at LiteDB.SharedEngine.CloseDatabase()
   at LiteDB.SharedDataReader.Dispose()
   at LiteDB.LiteQueryable`1.ToDocuments()+MoveNext()
   at System.Linq.Enumerable.SelectEnumerableIterator`2.ToList()

I tried researching this but haven’t come up with any ideas. Does anyone have any suggestions on why I’m getting this?

@a44281071 no this isn’t fixed in 5.0.12. Obviously multi-threading is complicated to get right. Unfortunately the readme file claims LiteDb is thread-safe, when it really isn’t fully (yet…).
