برطرف کردن مشکل Unknown StartTrace Error 183 در Exchange Server
Microsoft Exchange Server User Monitor (Exmon) is a great tool which helps to identity and troubleshoot basic issues on an Exchange server 2003, 2007 , 2010 and 2013. It collects very informative data in real time about the user activity, mailbox access, incoming requests and more details to locate the possible cause of the server issue. We have published an article that shows how Exmon helped to indentify the cause of high RPC/CPU usage and possible corruption of a mail box. Sometimes Exmon will crash while collecting and refreshing the real time data with ‘Unknown StartTrace Error (183)’ error and this article shows how to fix it.
By default Exmon does refresh the real time data every 1 minute automatically. If your Exchange server is already busy and loaded with high usage, then Exmon also will struggle to populate the real time data. It might crash with following message and give an error when you you open it next time. How to fix it? or how to open it again without the error?. Unfortunately you can’t find anything on the task manager or Windows services to kill the process. Restarting the Exchange server will work, but that’s not recommended at all.
