FIXED: x86_64: DEFRAGMENT MONTIOR /VOLUME DKA0: Crash

[pocketprobe]

I was creating a new virtual machine, wanting a clean install to get out of some baggage from my learning VMS. One of the products that I use on the machine is DFG. After most of my setup was done, I triggered a manual defrag and was curious about the monitor option. The defragmenter works fine, but the monitor for it crashes.

I triggered it with a manual

Code: Select all

defrag volume dla0:

And after the ui loads I end up with a screen that looks like

Code: Select all

This is with the only release of DFG for x86 which is DFG033-3.
If this is something that should be investigated, I can provide whichever info is needed.

[roberbrooks]

Yeah, I'm aware of this. It's on my list of things to work on.

Fixed; a new kit (V3.3-4) should be out shortly.

Interestingly, it was also broken on IA64, but not Alpha.

I guess the monitoring function is not too popular.

I don't know how much VSI think about it, but the hobbyist users do find a lot of bugs.

HP(E) hobbyist license was mostly VAX and Alpha.

VSI community license is mostly Alpha and x86-64.

There are very few Itanium hobbyist users.

Thank you for the very quick response on this.
I do a fair bit of advocacy and streaming my adventure with my internet friends. Plenty of homelabbers, but not too many run VMS in theirs.

It will be fun to see this run on my bare metal machine as well.

New kit is out! Works great, and with a trusty vt420 attached via a DECServer 90M over LAT to my bare metal machine. A warm anachronistic charm.

Thank you once more.
