Fun with WinDbg

I was looking into a Memory Leak  using a win-32 w3wp memory dump. Looking into the FinalizeQueue, I saw System.Data.DataTableCollection object in Gen2. Based on the hunch, I dumped the method table.

01

Dumped a couple of addresses listed above

02

I looked at the dataset and the _list, which brought me to the _items below.

03

The list of items is actually an Array.

04

Dumping the array and reviewing one of the array element(s) as below.

06

Viewing the value for tablename showed the string below. This is one of the objects used to retain Trace data.

07I am not posting the rest of the table structure, but if you are interested, you are welcome to follow the steps. Trace.axd was still active and ended up disabling it. Now back to looking into the actual issue.
