No Error Details Link on Error Log with Agents - With a 500 Internal Server Error

Question

I am running a small loadtest and recieving 500 Internal Server errors occasionally, however, there is no place to click details on the error log.  There is a view link under the stack for failed requests afterwards, however these requests where expected after the 500 errer.  So what determines if there will be a view link under Stack or Details for a particular request.  And is there a way to better log an instance (like when you run a single webtest) for each of the users in a load test.  It looks like there is for 2010, but not 2008 (which I am using).  The small load test I'm running has 5 conncurent users with 5 agents (1test/agent) and only 1 agents fails (gets the 500 internal service error) occasionally.  The inconsistant results seem to make it harder to debug.  I have the % of new users set to 100, and use a csv file to import 5 different users logging in.  Also, I cannot regenerate the 500 error if I do a single webtest run, it only occurs in a load.

Answer 1

I was able to get a detail window to come up after a few runs; there is a localization error, says "The process cannot access the file 'f:\inetpub\wwwroot\...\Main.asp.xml because it is being used by another process."

I would take a guess this is a race condition.

Hello NickN87,

Based on your description, there are some errors including the 500 Error.

 

Generally, 500 Internal Server Error indicates a failed request which could be caused by your webtest, load on the server,etc. I suggest you solve other errors first to see if this error remains.
