I'm trying to track down why but the network team cannot find an issue. We are able to reproduce the issue repeatedly by running "utils dbreplication runtimestate."

Has anyone investigated that? Do we know what this command is actually doing? Specifically, i want to know where it's getting those ping times... is it running a generic ping with generic datagram data? Is it sending a 1497 packet of 0x0000 and then 0xFFFF? Basically, I'm trying to give the network team something to go on because they are saying it's not them. (Of course they could run a packet capture and tell me (mostly) what it's doing, but it's hard to get their attention when they don't think it's on their end).<br></div><div><br></div><div>Thanks,</div><div>Nick</div><div><br></div><div>P.S. We have frequent DB replication issues... at least a few times per quarter. This is so annoying and I'm pretty sure it's due to this latency, but I can't get anyone to pay attention.<br></div></div>
