log4j：ERROR setFile（null，true）调用失败FileNotFoundException：/ETClient/log.log（没有此类文件或目录）

Question

即使我未提供任何此类文件路径，我仍在log4j配置中遇到“找不到文件”错误。我不是每次都会收到此错误。请在下面找到附加的堆栈跟踪。

[Table("MyEntities")]
public class DbMyEntity : IDeleted
{
    public string Name { get; set; }
    public DateTime? DateTimeDeleted { get; set; }
}

public interface IDeleted
{
    DateTime? DateTimeDeleted { get; set; }
}

public class MyContext : IdentityDbContext
{
    private Dictionary<Type, List<Expression>> dict = new Dictionary<Type, List<Expression>>();
    private Dictionary<Type, ParameterExpression> dictParameter = new Dictionary<Type, ParameterExpression>();

    private ParameterExpression GetParameter(Type type)
    {
        if (!this.dictParameter.ContainsKey(type))
        {
            this.dictParameter.Add(type, Expression.Parameter(type, "t"));
        }
        return this.dictParameter[type];
    }

    private void AddToDict(Type type, Expression expr)
    {
        if (!this.dict.ContainsKey(type))
        {
            this.dict.Add(type, new List<Expression>());
            this.GetParameter(type);  //Just to create ParameterExpression if not exists.
        }

        this.dict[type].Add(expr);
    }

    private void AddToDict<T>(Expression<Func<T, bool>> expr)
    {
        this.AddToDict(typeof(T), expr);
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {

        base.OnModelCreating(modelBuilder);

        foreach (var entity in modelBuilder.Model.GetEntityTypes())
        {
            if (typeof(IDeleted).IsAssignableFrom(entity.ClrType))
            {
                var member = Expression.Property(this.GetParameter(entity.ClrType), "DateTimeDeleted");
                var constant = Expression.Constant(null);
                var body = Expression.Equal(member, constant);
                this.AddToDict(entity.ClrType, body);
            }
        }

        //This is done in another project in same solution. See comment bellow.
        this.AddToDict<DbMyEntity>(t => t.Name == null || t.Name == "Something");
        //foreach (var builderType in allDllModules)
        //{
        //    if (builderType != null && builderType != typeof(ICustomModelBuilder))
        //    {
        //        var builder = (ICustomModelBuilder)Activator.CreateInstance(builderType);
        //        builder.Build(modelBuilder);
        //    }
        //}

        foreach (var item in this.dict)
        {
            var expression = item.Value.First();
            foreach (var second in item.Value.Skip(1))
            {
                expression = Expression.AndAlso(expression, second);
            }
            var lambdaExpression = Expression.Lambda(expression, this.dictParameter[item.Key]);
            modelBuilder.Entity(item.Key).HasQueryFilter(lambdaExpression);
        }
    }
}

我正在AWS lambda中运行此jar文件，没有像“ /Users/sgarretson/Desktop/mine/__a/source/ETClient/log.log”之类的文件。我仅使用控制台附加程序，未提供上述文件路径。我的问题是为什么log4j试图查找此文件以及从哪里获取此文件路径？
