SIG(0) checks quota reached ?

Hello all,

I just upgraded one of my machines (well fresh install to be exact…) from Debian 12 -> 13.

It’s now running BIND 9.20.11 (Debian package).

I have a few clients that use nsupdate to push changes to some dynamic zones.  This has gone through with 0 errors for years.  

This morning on one of the scheduled / triggered runs, my email from cron showed that the client was reporting “REFUSED” by my server.  However it seems like the update went through anyway ?  And right before it is the message in the Subject:

(Some names and IPs sanitized…)

Based on the timestamps it certainly looks related.  What does this mean ?

Thanks.
