I have had success in the past using HPjmeter to view these output files in a r...

Hi I used to generate thread dumps by running kill -quit and I would get them in a log file where my server logs were there. When the file grew too large I removed it using rm and created a new file of the same name. Now when I use kill -quit to take the thread dumps, nothing gets copied in the log file - its empty. Can anyone help? ...
