I'm using coLinux (andLinux precisely) to use my favorite torrent app, ktorrent.
Many of the times, coLinux keeps crashing in colinux-slirp-daemon.exe
I'll attach the crash logs.

the files you have send does not help to find the bug. It's a list of files only.
We need informations about the crash position in the file, an instruction pointer or current cpu register values. One or more hexadecimal address numbers related to the colinux-slirp-net-daemon. Perhaps you would find such in your Windows event logger. Or, from the window, you have seen the crash, open the option "more details".
THank you. I tried that. But Windows didn't allow me to copy paste that particular data. I'll see again to figure out how more info can be extracted. From my use, I can say is that colinux-slirp-daemon.exe is at fault. It keeps crashing very often. The crash is triggered especially when heavy network is done (I can't define how heavy. For me it was just a torrent app with 50-60k bandwidth utilization).
Crashes are ugly and bad. So I moved to native coLinux (I was using andLinux). Now, I've configured my network with WinPCAP in Bridged mode. My setup is now running for 12+ hours without any problems. I'm still using the same applications. Hence, I'm sure it is a bug with colinux-slirp-daemon.exe.
I'll try to reproduce the bug with the old setup once again and see if I can get the information that you're asking for.
And btw, thank you very much for coLinux. It is one great application I can give to my Windows colleagues to enjoy Linux.
I just looked into Event Viewer. There is nothing logged related to coLinux. :-(
I want to close this bug report because I moved to Bridge Mode, where I don't see the crash.
Even in slirp mode, this bug is reproducible under heavy load. While I can't define *heavy*, I don't think a lot of people are seeing this bug. So I'm closing it because I can't follow up on this atm.
I think this should be re-opened.
I've caused this to happen several times and it seems that the crash happens at the same point (i.e., same IP, dame call stack, same disassembly location, etc.)
The reason for this does seem to heavy network related, such as the case running bittorrents.
My setup is:
Slirp to connect to the Internet.
TAP to connect to the host and share files.
Windows XP SP3.
