SQL Server 2008, Server side trace disappears

What would cause a server side trace to disappear before I call exec sp_trace_setstatus @TraceID, 2?

On a local database, I'm using SQL profiler to export a server side trace definition. I'm setting the filename and running the generated script and the trace shows up as expected in

SELECT * FROM ::fn_trace_getinfo(default)

However, before my test harness finishes, fn_get_traceinfo shows the trace has disappeared and the trace file saved only matches the 1st half of the database workload. No errors are being thrown and I get the same results no matter what trace template I use. @@version is Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 开发者_如何学JAVA(X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Developer Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: )

Thank you.

In the event log I found

Trace ID '2' was stopped because of an error. Cause: Stopping the trace because the current trace file is full and the rollover option is not specified.. Restart the trace after correcting the problem.

At the top of the trace definition is a @maxfilesize variable, bump htat and problem solved.
