| Hmmm, seams my mud has come to hate my copyover/warmboots. I just installed Greven's version of this, and he will no doubt respond to this post! Anyways, I just had a little problem with mine. If you search back into my first problems on this forum, it was related to the locking up of after my copyovers. However, I was able to fix those. Now, after this, I did not manage to fix it. Now it is when I boot up the mud, and most likely when I hotboot also. Here's what its doing.
[odis@percy src]$ ps uxc
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
odis 8057 0.0 0.1 2960 796 ? S Mar04 0:00 hubstart

Now, notice the cpu usage when nothing is happening and the mud has just booted. Seems alright to me..so lets try and login. I connect and enter my name, all goes well. Next, password! Lets have a look at that cpu usage...

The important thing to note is that the cpu usage will continually go up until the game crashes (I watched it reach some 80% or so before I killed it).
I did rename my executable in hotboot.h. I have done everything according to the snippet, everything compiles fine, and now, this. I've tried getting rid of conjava and those (which were the evil little baddies last time), but to no prevail.
I'm off to tinker for a few minutes, please reply with suggestions.
By the way, the snippet can be found under the Resouces->Snippets section of darwars.wolfpaw.net and also at http://dementiasystems.com/swr/log.html, our SWR Snippets page. |

| Why it would lock up on copyover is quite baffling to me. Are you getting the "Enter your password" message, or is it just freezing after your enter your character name? If this is the case, sounds like something got messed up with load_char_obj, perhaps your supposed to have FALSE in comm.c as the extra bool, but instead have TRUE? Only a guess why this would happen during password...
Now, since this does not see to be a problem with the hotboot function itself, since you can't log in, I would say that load_char_obj is the most likely culprit.
How to figure out where its getting stuck:
go into your /area dir
enter "gdb ../src/<executable". This will load gdb and be targetting your executable in your source directory.
enter "run <port>" this SHOULD boot your mud normally, displaying the boot log to you.
Next, connect to your mud. You should, from what you said, get your greeting and be prompted for your name. Enter it, and follow what you did to cause the loop. When your sure that its frozen, go back to gdb, at hit "ctrl+z". This should stop the program where ever it happened to be during the loop. You can do a backtrace, "bt", and see where it got called from, and it should also give you the line that it was currently at. using "frame <number>", "up" and "down", you can go the place that it seems its looping, and print your variables using "print <variable>", or see the surrounding code with "list".
For a much more thourough and complete instruction on gdb, you can check Nicks guide, just do a search for it.
That should track it down for you, or give you better insight into the problem. I installed it on a stock SWR 1.0 with no problems at all, but since I wrote part of this version of the snippet, I may have missed a step in the instructions.
Please let me know what the problem was. Hope this helps. |

| | I'll run it through gdb when I get home. Something else I forgot to mention, it doesn't generate a core file. |

| | If its locking up, it won't create a core. Thats why the best way here is gdb. |

| | I think I found the problem. My pfile was HUGE! It turns out it saved my equipment a couple hundred times, so I think its a save problem. Off to investigate again. |
