Hello Bruce, I have not manually specified this property to enable udp encryption using "security-udp-dhalgo" anywhere. I am using TCP mode only.
Is it by default enabled? If yes, how can I disable it? I could not find any documentation on it.

I will surely open a JIRA soon. "Geode sends membership information, alerts and on rare occasions a PDX registration message over UDP" Would there be any negative impact on disabling 'security-udp-dhalgo' on peer to peer members or pulse or jmx notifications ?

Can you open a JIRA ticket to track this? Set the component to "membership". Looking at the unit test suite I don't think there is any coverage for auto-reconnect with security-udp-dhalgo enabled. As a workaround you could, if you're comfortable doing so, disable security-udp-dhalgo until this is fixed. There are other known issues with this fairly new setting that people have been working on recently. Geode sends membership information, alerts and on rare occasions a PDX registration message over UDP. No client/server messages are sent over UDP so its use is confined to your server cluster. No messages containing application objects (keys, values, callback args etc) are sent over UDP unless you set disable-tcp=true to disable use of tcp/ip stream sockets.
