When does the problem NOT occur?
Never. The problem is consistent.

Very sorry, we actually didn't properly check in the fix for this last time. We'll have a new build out shortly.

Lummox JR resolved issue with message:
Linux threading crashed some games on startup.
Jan 28 2014, 5:17 pm
I appreciate the assistance, you two :) I'll try it again soon and report the results, good or bad.
Jan 31 2014, 10:31 pm
Seems like this is continuing to crash, but except now it's not throwing out any error logs. On the bright side it's not crashing on server startup, it seems to crash a bit later. A bit being maybe like 10 minutes afterward.

Starting server with threads on.

Welcome BYOND! (5.0 Beta Version 504.1230)


That's the last log entry.
Feb 3 2014, 7:46 am
The fact that it doesn't say the server initialization finished means it's never completing startup for some reason. I'm not sure I can explain this, because it doesn't happen in my test setup. Using the Eternia code I have, I'm able to start up a server without incident.

I think at a minimum I'm going to need the latest copy of Eternia's source so I can re-compile and do a test on the newer source myself, as my test environment used older source. If you can zip that up somewhere and provide me a link in a private message I can try that.

Failure to startup is something that SilkWizard is also reporting in NEStalgia on just one system, so this is obviously a high priority to fix.

Is there a general rundown you can give me on what kinds of housekeeping the world does at startup? Anything like external connections, etc.?
Feb 3 2014, 8:52 am
Sent the latest source code.
Feb 3 2014, 2:15 pm
I'm getting the failure to start up too, in a project. It only occurs in Dream Daemon, never in Dream Seeker (when running it from Dream Maker).
Feb 3 2014, 4:32 pm
In response to Topkasa
The failure to startup is really a separate issue and we should probably continue on a new thread. However I'd have to know more about your project, and have access to source I can compile.

I tried several tests on Eternia today, and what looked initially like progress came up flat. I definitely need something that will reproduce this regularly. Are you having this issue on a Windows system, and if so, with which project? Is this something you can get to me to test?
Feb 3 2014, 6:57 pm
Mine is a "single-player" game meant to run in Dream Seeker. When run in Dream Daemon, it always fails to start the first time, but if I stop and restart the world, it will initialize correctly. It's the same project that's actually exhibiting the sound bug I've reported, too. If it would help, I can certainly send you the full source (as opposed to the stripped-down version in that thread)
Feb 4 2014, 6:31 am
In response to Topkasa
Yes, the full source would be quite helpful. Your issue sounds identical to Silk's, and I haven't made headway on that.
Feb 4 2014, 9:02 am
Alright, I'll send it to you tonight (~5-6 hours from now)
Feb 4 2014, 9:09 am
In response to Topkasa
Sounds good. I should be able to check it out after dinner then.
Feb 5 2014, 11:20 am (Edited on Feb 5 2014, 12:19 pm)
I'm having the same problem with Alternate Worlds, being unable to start it in single player on Seeker or on multiplayer in Daemon. The initial start of the server never seems to finish.
Feb 5 2014, 12:39 pm
In response to Mask of Illusion
As I mentioned, failure to start really needs to be a new thread. It's clearly not a crash or the same issue as the bug which was already fixed here. If you have source I can compile, I'll be happy to take a look and see if I can reproduce this issue. (I haven't had any luck so far.) I'd also like you to try adding some debugging output to world.log at the beginning and end of world/New(), and at various stages along the way in that proc, to see if you can narrow down where the startup fails.
