Short: Hyperborea crashes with corrupt memory
Date: Mon, 08 May 2000 18:58:41 +0200
From: Kees Leune <C.J.Leune@kub.nl>
Type: Bug
State: Done - machine error.
This is a series of mails describing a number of crashes on Hyperborea,
all but one in the swapper when swapping variables. The last crash is
in smalloc over a corrupted memblock guard.
It turned out that Hyperborea had a corrupted filesystem; with the move onto a
machine with a errorfree filesystem the crashes vanished.

Well.. probably you are right. But I need to be able to restart
the game automatically and I would not know how to do that with
gdb. Besides, most likely, the thing will dump core next time :(
> (Did I ask you what kind of system you are using, and if you have

No, you did not :) I have not make any modifications to the
driver. I am using a Pentium 90 with 32 Mb RAM on Linux installed
from a fresh Slackware 7 Distribution. Detailed information
enclosed below.
Personally, I have the feeling that there is something like a
buffer overflow somewhere, but I can't find the exact spot.

Hi Lars,
We crashed again, but this time there was a lot of potentially
useful debugging output. I attached the debug output to this
mail, so you can
look at it. Also, I did a backtrace with the core, which gives
these results:
Core was generated by `/home/games/hyperborea/bin/driver --mudlib
/home/games/hy
perborea/lib --master'.
Program terminated with signal 11, Segmentation fault.
Reading symbols from /lib/libm.so.6...done.

#0 fatal (fmt=Cannot access memory at address 0x31.

(gdb) bt
#0 fatal (fmt=Cannot access memory at address 0x31.

Hopefully, this will bring us closer to a solution to the
problem. Thanks for working on this!
Kees

Hi Lars,
We just had another crash. It almost seems like the driver is
getting more unstable every hour at the moment. Again, there was
no core dump. Here are the log files:

Dont worry about it. I have a similar workload at the moment,
which is why I kind of automated all guarding, log gathering and
restarting of the mud. All the effort I have to do it push the
'F'orward button and that's it :) I'll keep on sending you the
excerpts in that case.

I'll do that then. If this solves the problem, at least we can be
sure that the problem is in the swapper code.

*GRIN* our players will appreciate that :-)
Thanks!
