AX2012打开报表报错

AX2012打开报表报错：
格式化程序尝试对消息反序列化时引发异常: 尝试对参数 http://tempuri.org/ 进行反序列化时出错
The formatter threw an exception while trying to deserialize the message：There was an error while trying to deserialize parameter http://tempuri.org/:queryBuilderArgs.

错误原因：
Reason is when your report server or reporting AOS crashed or stopped without endding user session related to BC connector ,

OnlineUser's should be drained first before you take down your AOS .If its taking very long and your AOS is completely spiking kill the AOS process and then delete SysClientSessions records related to this AOS instance

and then , start all your services. Server draining should happen prior to AOS restart or else you will definitely end up with such issues. Happened to me several times

解决方法：
stop the aos first, delete all the records in table sysClientSessions, restart the aos and ssrs
