Hello guys, My server recently crashes and this is the ilog I got from the FMLE [PHP] Fri Jul 23 2010 09:32:21 : Primary - More than 50 % of the specified threshold values (Max buffer size 512000 KB or Max buffer duration 3600 sec) of RTMP buffer reached. Current network conditions are unfavorable to publish data at the specified bitrate. RTMP buffer will be flushed and streams will be re-published when the threshold value is reached. Fri Jul 23 2010 09:44:21 : Primary - More than 70 % of the specified threshold values (Max buffer size 512000 KB or Max buffer duration 3600 sec) of RTMP buffer reached. Current network conditions are unfavorable to publish data at the specified bitrate. RTMP buffer will be flushed and streams will be re-published when the threshold value is reached. Fri Jul 23 2010 09:56:21 : Primary - More than 90 % of the specified threshold values (Max buffer size 512000 KB or Max buffer duration 3600 sec) of RTMP buffer reached. Current network conditions are unfavorable to publish data at the specified bitrate. RTMP buffer will be flushed and streams will be re-published when the threshold value is reached. Fri Jul 23 2010 10:02:21 : Primary - RTMP buffer exceeded the specified threshold values (Max buffer size 512000 KB or Max buffer duration 3600 sec). Flushing the RTMP buffer and re-publishing the streams. Fri Jul 23 2010 10:02:26 : Primary - Network Status: NetConnection.Connect.Closed status Fri Jul 23 2010 10:02:26 : Primary - Disconnected Fri Jul 23 2010 10:03:26 : Primary - Connection failed [/PHP] It seems after it reached 100% RMTP buffer threshold, the server crash. Is there a way I can increase this threshold to prevent future crash? This server is a live\_repeater and edge\_server, also a loadbalancerlisterner and loadbalancersender Thanks ---

Did Wowza crash? These FMLE logs show that Wowza sent “NetConnection.Connect.Closed” notification. So Wowza sent the client this message, which indicates that it was running. You should be able to find the corresponding line in the Wowza logs. You could start by looking for the publish log line in the log and seeing the encoder’s clientID is, then looking forward to where Wowza disconnected that client. Then look at what happened before and after that point. You also should setup JMX/JConsole to monitor the server. Richard ---

That is probably something unrelated to Wowza or FMLE. Richard ---

Looks like Wowza dealing with network problems with a stream it is publishing. Richard ---

Hello, The whole server crashed, not just wowza. When it crashed, all sites down, all services shut down and I can not access the server via Putty anymore. I had to restart the server via IP KVM. It has happened several times during the last 3 days. I will look into what you suggest Thanks ---

What do those lines mean? [PHP]Fri Jul 23 2010 09:32:21 : Primary - More than 50 % of the specified threshold values (Max buffer size 512000 KB or Max buffer duration 3600 sec) of RTMP buffer reached.

Flushing the RTMP buffer and re-publishing the streams. [/PHP] I notice that after RTMP exceed the threshold, it will crash the server. Please look at the time line. The server was crashed just 5 second after the RTMP exceed the threshold. Maybe I will look into the max buffer size 512000 KB ---

The server was crashed just 5 second after the RTMP exceed the threshold. Maybe I will look into the max buffer size 512000 KB Hello phattran911, I have the exact same issue as you. Did you ever figure out what is causing this? Any help would be greatly appreciated. Thank you.
