Hi all,

https://smedley.id.au/tmp/named.map

Thanks.  This helps.

Looking at the appends stack traces for all the threads, there are a
couple of possible reasons for the hang.

The thread a slot 5b is waiting on a select() to return.  However, this
select has no timeout value defined.

You might notice that a couple of the threads are waiting to acquire a r/w
lock on some data.

Massimo, I need to see two more dump files.  The first taken after you
notice named has hung and the second taken after you have attempted to
kill named.  With a bit of luck, this will help us figure out why the kill
fails.

Paul, how much work would it be to build named.exe with debug symbols?

Easy enough.... https://smedley.id.au/tmp/bind-9.11.37-os2-debug-20240524.zip
