We have several Dell 6224 and 6248 switches running 3.2.1.3 through 3.3.9.1 firmware that occasionally experience poor performance all at once.
When this happens, there is an info message that repeats three times per second in the buffer log: component VOIP - VoipPktIntercept(): message send failed. While this is happening pings to the management IP for layer 3 switches are over 500ms and over 50ms non-routing switches.
The error does not resolve by unplugging all the devices from the ports. The only way to correct the issue is to reload the switch.
Auto VOIP mode is disabled. Some switches have never experienced the issue while others have the issue often.
I feel that some type of traffic that may be causing this but I do not know where to start or how to more gracefully mitigate the issue. Any help would be appreciated.
Thanks
Kurt
