Are you sure the webserver has rights to write to that directory? And
can you please check if Xdebug is actually loaded properly in the
webserver (check phpinfo() output)?

That's most likely because the default configuration uses the PID of the
process in the filename. You need to configure it such that the
filenames are the same for each request, for example by using the %s
modifier (See http://xdebug.org/docs/all_settings#trace_output_name).
