if this can help, the same bind build on the other VM 2 cores is not
showing the issue (this VM instead has 8 cores assigned), dunno if this
is due to SMP

An SMP race condition is always a possibility, especially on faster
systems with lots of cores.

You can always try marking named.exe as MPUNSAFE and see if this helps.

i do not find this "MPUNSAFE" on hobbes neither on warp cave.

Hi,

thanks, but i need the tool.
I've not found any download link.

No, you already have this.

So, assuming you are in the directory with named.exe and markexe.exe is in %PATH%:

markexe MPUNSAFE named.exe <Enter>

That's how you "mark" "named.exe" as "MPUNSAFE"

If you run:

markexe /?

you'll find out lots of neat things it can do.

Verify that your marking is in effect with:

markexe DISPLAY named.exe

which should (among other things) list MPUNSAFE.

You've been doing this stuff a while, so I'm surprised this was not more obvious to you.

BTW, if you don't have the toolkit installed for some reason (Arca Noae does not distribute the toolkit with ArcaOS, as it is not part of our licensing agreement with IBM), you may install the toolkit from RPM (yum install os2tk45 or use ANPM). Note that the Netlabs RPM distribution does not install the toolkit to the "expected" location, but the binaries should be locatable.
