Dear support,
we are experiencing this issue for years. Switches powerConnect 6224 and 6248 occasionally suffer lost of performance and finally get stuck. In the log we can read several messages like this:
VOIP[103498576]: voip_control.c(179) 10946 %% VoipPktIntercept(): message send failed
The only way to recover the switches is rebooting from console or hardware reboot.
We have tried to update the firmware, disable auto VoiP, replace the units, etc. without success.
Now the units are two stacked 6224 with 3.3.4.1 firmware and RSTP.
We have similar configurations with the same firmware at other sites without issues. Any help would be appreciated.
Thanks,
