Thanks for that comment, but the trace is actually writing to a file on a separate physical disk, the the StopPerfTrace SP reads it in using fn_trace_gettable.

For what it's worth, I came into databases from development. I got into development after film school and four years in the Navy as a nuclear power monkey mate. I...

I will also self-promote, but only after I promote a couple of others.
There are three books that I really like that deal with being a DBA, not so much SQL...

I just left a company that did a number of migrations. We had very few issues. Most of the time the problem was in code that was deprecated. Be sure...

I see the trace is outputting to a table, is that right? If so, is it a table on the system that you're doing your testing on? That could be...

Expire date doesn't determine how many days are kept. That's a marker for old style tape backup systems.

It sounds like you have the issue isolated to a particular table. What queries are running against the table. I'd focus there. Most of the time, problems exist either in...
