How to know the generated trace file is valid

[guangcheng liang]

Hi,

When I use taint_file instruction to get trace files, I have encountered many problems. Finally, I get the trace file of software called WPS which can handle doc files like Microsoft office but is much smaller than micro office, and the size of the trace file I get is 3.5G. I think the size is neither too large nor too small. Then I tried to use the instructions as follows in Vine to generate stp file.

./trace_utils/appreplay -trace examples/wps.trace -stp-out wps.stp

But after several hours, the above instruction seems still running and the computer run very slow. So I began to doubt that if the generated trace file is valid.

I have successfully got the trace file of a small program written by myself using the above instruction and also get the expected result by querying STP.

Thanks very much for your attention. I will be thankful for any suggestions.

3.5G. - it's very big.
in my test - i can processed trace size less 500M
