Well, how large are the files now?
Usually the file size is limited to 10 MB. After that the process writing into them switches to a new file.
You can check the current settings in parameter file global.ini • [trace]:
maxalertfilesize: 50000000
maxfiles: 10
maxfilesize: 10000000
Just change the maximum size of trace files to what you consider better.
Besides that there is no supported way to force a switch for the trace files.
And again: what's the point? 10 MB is not terribly large and having more files doesn't make it easier to deal with them...
