it seems dead lock #118
Description
we use 0.6.0.0 and used like this:
public byte[] Serialize(T data)
{
using (MemoryStream stream = new MemoryStream())
{
// Creates serializer.
var serializer = SerializationContext.Default.GetSerializer();
// Pack obj to stream.
serializer.Pack(stream, data);
return stream.ToArray();
}
}
public T Deserialize<T>(byte[] data)
{
using (MemoryStream stream = new MemoryStream(data))
{
// Creates serializer.
var serializer = SerializationContext.Default.GetSerializer<T>();
// Pack obj to stream.
return serializer.Unpack(stream);
}
}
the Generics T now is:
[Serializable]
public class OrderLockingInfo
{
public OrderLockingInfo()
{
this.LockedBy = string.Empty;
}
public long OrderId { get; set; }
public bool IsLocked { get; set; }
public DateTime LockedDate { get; set; }
}
our Webapp host in IIS 7.5 base above codes crashed with memory Growing to top.
with the dump file, we saw almost are the belowe stack:

it seems the same Type Serializer object is lock the other thread is waiting.
