 last string contains to big chunk!!!

 about once a day, sometimes such a problem that the chunks stop being
 generated and ffmpeg starts to write everything in one file, but the
 playlist continues to be updated and the chunks in it are recorded. The
 new are not created, as all is written in one file. And in the nginx logs
 written error that file not found. The server runs about 250 threads
 ffmpeg. But mostly this error occurs with HD streams.
