We are using Wowza3 to record 20 live streams with wms-plugin-livestreamrecord.jar module.
All goes good, but every 50 minutes even at night when there is no users online we have peaks of I/O operations on our disk.
Writing speed is constant all day (~ 64 Mbit/s) and it is normal. But reading peaks grows till 200Mbit/s and have durations ~ 15 minutes. So every 50 minutes it reads volume like 20 Gb. And looks like that it re-reads all that was written for this period.
What wowza can do in this time?
How to discard this not rationally disk usage?
