Dude 3.0 Random Ping Failures

Sep. 25, analog reported:

Running RC3, I am starting to see random devices report down when they really aren’t. Re-probing them immediately shows them up. It appears this problem isn’t completely solved.

I’m getting the same symptoms with Dude 3.0. I added FTP, SSH, and Telnet to the polling, and they all report that the device is up. I’m Running W2KSP4, monitoring RB133C’s and RB133’s running ROS2.9.46 and 2.9.51.
