Anyhow, I have a set of logfiles now, and I have looked them all over, and there doesn't seem to be a command that is taking the server down. The last crash was after a prolonged period of no chat commands, as far as I can see. Is there another logging option in NWNx I can set to get more info?

You could use the profiler plugin and set it to full logging. That generates a lot of data, but you might spot a certain script that runs just before a crash.

if thats what it takes, then so be it. I need to know what script is taking this thing down.

Alright, I have some serious data now, but I cant see a script that is causing the crash. The profiler has been running for 2 days. There was one crash in that time.

The broken script is basically the last script in the log.
But it can be some rare bug in NWNX. Only core dump+gdb can tell (in Linux.. I don't know much about core dumping in Windows). For example, last week I discovered a strange bug when NWNX tried to call OnRequest from non-existent library (the data at the pointer definitely wasn't a NWNX library class). I still haven't found out what made the Libraries class return that incorrect pointer as well as couldn't reproduce it.

Well, I can definitely find that broken script if'n thats the problem.

I will post what I find when I get a sec for looking.


Edit:

I am looking at the logfile, and the last script in the stack is fky_chat

That's not what I was hoping to see. Well, at least I know what script to look into, I guess.

What that means, of course, is that a speech event triggered the crash, almost definitely due to some script conflict, though possibly to an issue with the plugin itself, or the scriptset. I would enable the text logging, and move it up to the top of the scriipt (after the needed info is retrieved), in hopes of catching the problem text and getting it logged before it causes the crash. Also might want to alert your players to the problem, one of them may remember typing something just before the server downs. It's also possib;e you have a malicious user overloading the chat buffer to crash the server when they want (to dupe, or for whatever reason). I was planning to add an option in SIMTools to guard against that, basically just a length cap on a mesage before it was autosuppressed - you could try adding such a limiter, but I would make the limit good and long if you do. (Send me a PM if you want to learn more about chat buffer crashing). Judging by the onset coinciding with SIMTools though, I spose it's more likely the script or plugin.

There was a bug in NWNX Chat that could cause these crashes. It was discovered and fixed yesterday, but due to technical problems with one of my hard drives I can't access Windows sources now.

Nice! When will the updated linux version be available? Nice catch, and nice fix, both of you!

That may actually be the best news I have gotten all day

Who'da thunk a bug could ever be good news?

Personally (yes I know the above PM mention was to virusman) I am not too worried about the players crashing the server using chat commands. We have a pretty good bunch on there, and they don't seem the type. If it becomes a problem, I will contact you.

Anyway, I'll fix the chat buffer overflow bug as well.
