I am new to nsd and have been setting up a few servers to eventually replace my bind servers. Things have been going reasonably well; most problems have been of my own making. This may be another instance of that, but I would like to double check. I noticed that in the log file zones appear to be transferring repeatedly, every few minutes. For example:
[2021-07-29 13:17:54.719] nsd: info: axfr for jxxxxxxxxxy.com. from 5x.xx.xxx.8
[2021-07-29 13:22:46.880] nsd: info: axfr for jxxxxxxxxxy.com. from 5x.xx.xxx.8
[2021-07-29 13:27:20.024] nsd: info: axfr for jxxxxxxxxxy.com. from 5x.xx.xxx.8
2021-07-29 13:32:11.180] nsd: info: axfr for jxxxxxxxxxy.com. from 5x.xx.xxx.8
I've tried to sanitize things a bit, but that is the same zone being transferred to the same secondary server every 4 to 5 minutes. This is happening for all of my zones and all of my secondaries.
1. Am I interpreting that correctly?
2. If yes, Is that normal behavior?
3. If no (to #2), what have I likely misconfigured?
Please let me know if I should provide any additional information.
