WCF服务为什么会经常崩溃呢
我是个WCF的初学者，在服务器上架构一个WCF服务，客户端在调用WCF服务的时候如果只开一个就正常
但是如果开了9个以上就会崩溃了~必须重启WCF服务才行
哪位大大可以帮忙看下是啥为题啊~
[最优解释]
没几句代码注释，高手啊！！！
[其他解释]
连接数一增加之后系统崩溃之后，如果再去连接WCF调用某个方法返回的值可能是别的方法的返回值
也就是说可能返回两列的表，也可能是三列的表~
相当吐血，感觉好像服务紊乱了~

服务契约的实现：
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall,IncludeExceptionDetailInFaults = true,ConcurrencyMode = ConcurrencyMode.Multiple)]
public partial class ArchieveContract : Artech.WcfServices.Service.Interface.IEmployees
{
private static IList<Artech.WcfServices.Service.Interface.Employee> employees
{
get
{
if(1==1)
return EmployeesServiceArchieve.employees;
}
}
public Artech.WcfServices.Service.Interface.Employee Get(string id)
{
return EmployeesServiceArchieve.Get(id);
}
public void Create(Artech.WcfServices.Service.Interface.Employee employee)
{
EmployeesServiceArchieve.Create(employee);
}
public void Update(Artech.WcfServices.Service.Interface.Employee employee)
{
EmployeesServiceArchieve.Update(employee);
}
public void Delete(string id)
{
EmployeesServiceArchieve.Delete(id);
}
public IEnumerable<Artech.WcfServices.Service.Interface.Employee> GetAll()
{
return EmployeesServiceArchieve.GetAll();
}
}

{
IHourDataChannelArea = GetChannel<IHourData>();
}

catch

这个是自己测试用的代码，没必要加注释~
[其他解释]
崩溃的现象是什么？有没有错误信息/异常信息可以参考？
[其他解释]
tcp 有最大连接数限制。google一下吧。
[其他解释]
最大连接数我有改成netTcp.MaxConnections = 1000;
[其他解释]
忘了说明下我是把WCF寄宿在windows服务里面的~
[其他解释]
windows 自己也有连接数限制呀。比如 XP 就是 10个。查查。
