When reading EPiServer CMS logfiles it returns many rows, but when troubleshooting you probably only wants to examine the tread that causes the error. To examinethat I usually and filter out a thread that causes the exception.
I use
Cygwin coammands to read my logfiles.
Example
In the log file I can see
2009-04-30 11:39:53,581 ERROR [4] EPiServer.Global.Global_Error - 1.2.5 Unhandled exception in ASP.NET
The tread number [4] is causing the error.
Then I list the log file and filter out all messages generated by thread number [4]
Cat EPiServerErrorLog.txt | grep ‘\[4\]’
And at the end I can see
2009-04-30 11:39:56,533 DEBUG [8] EPiServer.Web.UrlRewriteModule.HttpUrlRewriteToInternal - Returning URL http://localhost:50017/favicon.ico
I missing my favicon.ico file.
