Problem with too many open files #1

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
It seems that TSAB doesn't close all resources properly.
After some time (a week or so with very moderate usage (10 people per day)), 
the following exception is reported in the log file:
SEVERE: Servlet.service() for servlet TsabAudioDownloadServlet threw exception
java.io.FileNotFoundException: 
/home/webspeech/tsab/audio/vastasseis20101217##001.mp3 (Too many open files)

This in turn causes all sorts of other problems, e.g.:
