Well, aMule crashed, that's the idea. Pelase provide a backtrace. Take a look at http://www.amule-project.net/amule/thread.php?threadid=298&sid=
Thanks a lot.
Greetings!

I've lost my internet connection too, and amule crashed...

So I tried to do it manually to test and.. well, it crashed again. I guess anyone can reproduce this...

Actually, it first crashed when my internet connection (pppoe) got lost, and disappeared even from Gkrellm. My adsl line just returned some minutes later...

And to confirm it, I did switch my ADSL modem off, and... well it happened again.



Unfortunately, I can't post the backtraces because... I'm using Debian packages and I don't want to mess my system up installing non-packaged things (having to compile emule with debug) :P

Kournikola, if you could do that... please do it for us :P

well, it's just a guess  ?( but i suspect it's first amule hanging your modem

i experienced similar problems when switching from a precompiled rpm package to self compiled versions of amule:
- modem losing connection 30 min - 8 h after amule has been started
- amule crashes in some versions, keeps running in others (i tried 1.2.4-1.2.6 and 2.0.0rc2
   on SuSE 8.2 and Fedora Core 1)
- modem does not reconnect in most cases without being resetted
- in those few cases when modem reconnects by itself, it reconnected at ISDN speed or less

i didn't experience these problems with other apps (browser, download manager) when not running amule, nor with the rpm package; on the other hand, with self compiled amule running, in many cases my connection was gone when the browser started loading a page, so i suspect amule is somehow confusing the modem (the changelog of 2.0.0rc3 mentions something about the possibility of amule hanging up modems)

i tried the following workarounds:
(1) using very conservative settings, reducing max connections to 100 or less, reducing max connection per 5 sec to 10 --> little improvement
(2) compiling amule with --disable-optimise --> the connection stays up significantly longer, but nor forever (in fact, the rpm i had been using and which had been running without those problems had consumed up to 70-95%(!) of my 1300 MHz CPU)
(3) running "ping some.server.com" in the background - seems to help keeping the connection alive for some time longer
(4) swapping modems & network cards --> wouldn't help

i finally tried a cvs amule - voila, problem gone:
cvs 2004-06-22 has been up & running without problems for 40 (forty) hours now without crash & without losing connection, so i recommend you try that one (indeed very close to rc4 !!!) :D
