Hi HarikiTsuyoshi,
Can I have the information, so that I can reproduce the problem with
4.1.20? I would like to reproduce it, so that I can debug (get a stack
trace and perhaps more debugging) the reload process. (process 2939 in
your logs). Perhaps the zone file (old & new?) is sufficient to reproduce?
In 4.1.20 there is 'make xfr-inspect' in the source that builds a tool
to inspect the contents of the xfr file from /tmp, and that file could
be interesting (it contains the downloaded zone update, and perhaps it
can be used to reproduce the problem).
Best regards, Wouter
