Could you please describe what happened for your shard to crash?

Have you made any modifications to your core?

Here is my private class EntityEnumerator : IPooledEnumerator<IEntity> method is yours the same?

Code:

private class EntityEnumerator : IPooledEnumerator<IEntity>
		{
			private Map m_Map;
			private Rectangle2D m_Bounds;

			private int m_xSector, m_ySector;
			private int m_xSectorStart, m_ySectorStart;
			private int m_xSectorEnd, m_ySectorEnd;
			private int m_Stage;
			private IList m_CurrentList;
			private int m_CurrentIndex;

			private static readonly Queue<EntityEnumerator> m_InstancePool = new Queue<EntityEnumerator>();

			public static EntityEnumerator Instantiate(Map map, Rectangle2D bounds)
			{
				EntityEnumerator e = null;

				lock (m_InstancePool)
				{
					if (m_InstancePool.Count > 0)
					{
						e = m_InstancePool.Dequeue();

						e.m_Map = map;
						e.m_Bounds = bounds;
					}
				}

				if (e == null)
				{
					e = new EntityEnumerator(map, bounds);
				}

				e.Reset();

				return e;
			}

			public void Free()
			{
				if (m_Map == null)
				{
					return;
				}

				m_Map = null;

				lock (m_InstancePool)
				{
					if (m_InstancePool.Count < 200) // Arbitrary
					{
						m_InstancePool.Enqueue(this);
					}
				}
			}

			private EntityEnumerator(Map map, Rectangle2D bounds)
			{
				m_Map = map;
				m_Bounds = bounds;
			}

			public IEntity Current { get { return (IEntity)m_CurrentList[m_CurrentIndex]; } }

			object IEnumerator.Current { get { return m_CurrentList[m_CurrentIndex]; } }

			void IDisposable.Dispose()
			{ }

			public bool MoveNext()
			{
				while (true)
				{
					++m_CurrentIndex;

					if (m_CurrentIndex == m_CurrentList.Count)
					{
						++m_ySector;

						if (m_ySector > m_ySectorEnd)
						{
							m_ySector = m_ySectorStart;
							++m_xSector;

							if (m_xSector > m_xSectorEnd)
							{
								if (m_Stage > 0)
								{
									m_CurrentIndex = -1;
									return false;
								}
								++m_Stage;
								m_xSector = m_xSectorStart >>= SectorShift;
								m_ySector = m_ySectorStart >>= SectorShift;
							}
						}

						m_CurrentIndex = -1;

						if (m_Stage == 0)
						{
							m_CurrentList = m_Map.InternalGetSector(m_xSector, m_ySector).Items;
						}
						else
						{
							m_CurrentList = m_Map.InternalGetSector(m_xSector, m_ySector).Mobiles;
						}
					}
					else
					{
						IEntity e = (IEntity)m_CurrentList[m_CurrentIndex];

						if (e is Item)
						{
							Item item = (Item)e;

							if (!item.Deleted && item.Parent == null && m_Bounds.Contains(e.Location))
							{
								return true;
							}
						}
						else if (e is Mobile)
						{
							Mobile m = (Mobile)e;
							if (!m.Deleted && m_Bounds.Contains(e.Location))
							{
								return true;
							}
						}
					}
				}
			}

Please argalep don't post every problem with your server in bug reports, add in either script support or windows support

IF it turns out to be an actual bug then we can move it.

Argalep · Sep 7, 2014

I'm sorry milva,

Omni crash line is 1399

Code:

public bool MoveNext()
			{
				while (true)
				{
					++m_CurrentIndex;

					if (m_CurrentIndex == m_CurrentList.Count)
					{
						++m_ySector;

						if (m_ySector > m_ySectorEnd)
						{
							m_ySector = m_ySectorStart;
							++m_xSector;

							if (m_xSector > m_xSectorEnd)
							{
								m_CurrentIndex = -1;
								return false;
							}
						}

						m_CurrentIndex = -1;
						m_CurrentList = m_Map.InternalGetSector(m_xSector, m_ySector).Clients;
					}
					else
					{
						Mobile m = m_CurrentList[m_CurrentIndex].Mobile; // line 1399

						if (m != null && !m.Deleted && m_Bounds.Contains(m.Location))
						{
							return true;
						}
					}
				}
			}

Mobile m = m_CurrentList[m_CurrentIndex].Mobile;

What version are you using? Servuo? Runuo Rc2? Rc1? Svn?
How is the crash made?
Have you made core changes?

Your mobile.cs is quite different from mine and im running all the latest content on servuo..

Argalep · Sep 7, 2014

Servuo Publish version 54.59

I do not know how the crash happened. Core script no change.

Milva · Sep 7, 2014

For future reference this helps to create a much better crash report- http://servuo.com/threads/how-to-how-to-run-your-server-in-debug-mode.1184/

Hey !

I used to have the same crash ...

For those encountering the same bug, here's my fix :

Code:

	public bool MoveNext()
			{
				while (true)
				{
					++m_CurrentIndex;
 
					if (m_CurrentIndex == m_CurrentList.Count)
					{
						++m_ySector;
 
						if (m_ySector > m_ySectorEnd)
						{
							m_ySector = m_ySectorStart;
							++m_xSector;
 
							if (m_xSector > m_xSectorEnd)
							{
								m_CurrentIndex = -1;
								return false;
							}
						}
 
						m_CurrentIndex = -1;
						m_CurrentList = m_Map.InternalGetSector(m_xSector, m_ySector).Clients;
					}
					else
					{		
						if (m_CurrentList.Count == 0)
							return false;
 
						if (m_CurrentIndex > m_CurrentList.Count)
							return false;
					
						Mobile m = m_CurrentList[m_CurrentIndex].Mobile;
 
						if (m != null && !m.Deleted && m_Bounds.Contains(m.Location))
						{
							return true;
						}
					}
				}
			}

It might come from a mod ... not sure it's ServUO related

Cheers,

-Rek-

very clever solution. But if I find that which stems from the creature, I'm very relaxed. Thanks you..

Is that a riddle?

Milva · Sep 10, 2014

argalep did you get your problem fixed? If so you might post how you stopped the crash in case some one else has this problem

Do you believe this was a bug with servuo?

Argalep · Sep 26, 2014

if (m != null && !m.Deleted && m_Bounds.Contains(m.Location))

fixed

Regnak · Sep 28, 2014

I'm not sure it's the right fix ...

The line 1399 in your file is before the line where you put your fix.

But if you say it's ok, good for you
