Strange Shared_Memory issue

[provocating]

Moving my server between Debian installs I am getting a new shared memory error. The directory is there, just called "shared". I have tried giving permissions as the user and even run shared_memory as root and still get the same errors. Strangest thing...

Looking at line 112 that is definitely where it is trying to open the file. I am at a loss here, unless there is something drastic between Debian versions.

Where are your files and what are your permissions? Are you using symlinks? Give an ls -al on your emu root folder?

So all owned by root:root. What happens when you run ./shared_memory all by itself as root?

[provocating]

It runs as normal and fills the directory, all files have sizes

I pretty well set my debugging to max, so I am getting plenty of data back when zone runs.

Eww running as root.

[joligario]

I'm wondering if this is a nesting permissions issue. Is your original user eq1? I recommend going back and chowning everything (-R from src) back to eq1, clear locks/logs, rebuild and run everything as that user again.

EDIT: Haha, demon and I were thinking the same thing...

Never, that was just for troubleshooting, I know better.

[Akkadius]

provocating, run this and try again:

UPDATE `variables` SET `value`='' WHERE (`varname`='hotfix_name')

Let me know how this works for you

[provocating]

That did it. Now I am completely confused why that would have any effect at all. Should this be something I include in a reboot script?

[Akkadius]

It's kind of a "bug", it's working as intended but its an issue that folks run into when they make use of #hotfix.

I'll look into making a long term solution for it.

[provocating]

If you can enlighten me on what is causing it, I would like to go ahead and change it in my source. I use hotfix at least a few times a day.

I'm working on it right now, calm your tits

[Akkadius]

Done and tested.

Works.

Profit.

Love me long time
