Hi. It has been a while since I checked here. But something came up that I hope someone might be able to help. I have a Freeaxp installation on a Windows system that has been running for several years. It suddenly stopped, and attempts to reboot result in:
(boot dka0.0.0.6.0 -flags 0)
block 0 of dka0.0.0.6.0 is a valid boot block
reading 1230 blocks from dka0.0.0.6.0
bootstrap code read in
base = 1f2000, image_start = 0, image_bytes = 99c00
initializing HWRPB at 2000
initializing page table at 1e4000
initializing machine state
setting affinity to the primary CPU
jumping to bootstrap code
I saw that link, and since it seems like it may be a VMS issue, I am comparing the current VMS params with earlier backups... Also looking for potential disk problems. But in case there is a clue in the logs. here is one where the boot fails. I don't see anything obvious. Sorry, it is long.

I've been experimenting with clusters and cluster-wide shadow sets, and I somehow ended up booting the FreeAXP node using the wrong system root, which has a configuration for a much larger (DS10) system, so obviously ran into issues on working set sizes. Once it booted to the proper system root, it booted fine and joined the cluster. This was setup a while ago, and since once started, VMS just keeps on going, when the node died and I needed to restart it, my @home mind forgot the proper steps. Sigh.
I did download and install the latest FreeAXP, and of course the behaviour was the same. I am considering making the change to the new version (I ended up back on 126.96.36.1994 on the active node) to see if it has better performance? And I will like to try the multiple instances on a single box. Imagine a 100 node cluster on a couple dozen 8-core boxes! Useful? Probably not, but might be fun to try (if I could afford it ;-)
Thanks for the help. My apologies for taking you down a rabbit hole with me.
