Hi,

I have installed Wowza 4 in a Centos server. But after installation, I am seeing below messages: What does it mean, how can I remove them

Hi,

Could you try the following and see if these alerts go away:

- navigate to /usr/local/WowzaStreamingEngine/stats

- delete the files in that directory ( rm /usr/local/WowzaStreamingEngine/stats/\*)

- restart Wowza.

Wowza will recreate the stats database files once it is back up. If the alerts continue to happen then please raise a ticket by emailing your findings to support@wowza.com, including a link to this thread and zipped up copies of your [install-dir[/conf/ and [install-dir]/logs.

Kind regards,

Paul
