Hello!
I recently found out that my logs are FULL of these:
....

....
a) what does this actually mean?
b) I am fighting a certain sluggishness especially in relation with
transactions. Could this be the cause? What could I do to improve the
situation?
Just for illustration the BannerPosition class:
public class BannerPosition : NamedEntityBase<Guid>
{
private readonly ISet<Banner> banners = new HashedSet<Banner>();
private readonly Random r = new Random();
protected BannerPosition()
{
}
public BannerPosition(string name)
: base(name)
{
}
public virtual ReadOnlyCollection<Banner> Banners
{
get { return
SetManager<Banner>.GetSetAsSortedReadOnlyCollection(banners); }
}
public virtual uint Hits
{
get { return (uint) banners.Sum(b => b.Hits); }
}
public virtual void AddBanner(string imageSource, string url, string
text)
{
SetManager<Banner>.Add(new Banner(imageSource, url, text),
banners);
}
public virtual void RemoveBanner(Guid id)
{
var banner = banners.Where(b => b.Id == id).SingleOrDefault();
if (banner != null)
SetManager<Banner>.Remove(banner, banners);
}
public virtual Banner GetRandom()
{
var bs = banners
.Where(b => b.IsActive)
.ToList();
if (bs.Count == 0)
return null;
if (bs.Count == 1)
return bs[0];
var idx = r.Next(0, bs.Count);
return bs[idx];
}
}
and it's mapping (generated by nhf)

Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"
