Technically not a crash but it hangs
« on: May 12, 2005, 11:34:04 AM »

Hi,

Since I am running FC2 I am unable to install rpms for it. I downloaded source for amule 2.0.0 and compiled it myself. I've also installed generic version of wxGTK 2.6 rpms (downloaded from this site). First impresion was good. I've let amule run for whole night and in the morning I can see that it is hanging, i.e. the process seems to be stack in some kind of loop, totally unresponsive, no download, cpu usage at 75%-100%, etc. Main window is still there but completely blank, nothing in the log. Oops, I think, surerly this must be a problem with wxGTK. No time to experiment so I run amuled. Cool, no crashes, no hangs but UI sucks (sorry guys). So I started playing againg with amule. Downloaded wxGTK sources, compiled, installed, ran amule and .... still hangs. I have no idea what this could be. It runs perfectly for few hours and then bang. Next step is to compile debug ver and when it hangs attach to it and see where is stuck. But it takes time and my vocational duties prevent me from spending to much time on this.

Any idea what this might be? I'd really appreciate some help.

Cheers,
Mikey

I use standart 2.0.0 source. There is nothing on the console or in the logs (I mean nothing that could be useful). I am going to compile debug version tonite.

One more thing, to compile amule I used standard config:

./configure --prefix=/usr --enable-optimize --disable-debug --enable-wxcas --enable-cas --enable-alc --enable-alcc --enable-amule-daemon --enable-amulecmd --enable-amulecmdgui --enable-webserver --enable-webservergui --enable-amule-gui

One more question, what does --enable-maintainer-mode do exactly?

Please read this:
http://www.gnu.org/software/automake/manual/html_node/maintainer-mode.html

Now that you mention, I think that this option sucks. Kry, what about removing AM_MAINTAINER_MODE from configure.in? It is in the file since aMule initial CVS import.

Quote
From the automake docs
Jim Meyering, the inventor of the AM_MAINTAINER_MODE macro was swayed by Fran├žois's arguments, and got rid of AM_MAINTAINER_MODE in all of his packages.

Thanks Phoenix, I am not a Linux guru, most of my professional work is around Solaris and embedded systems running VxWorks for example, so GNU autoconfig is a bit of a mystery for me :D But I'll manage somehow ... I'll try to debug this problem either today or over the weekend and will post results. In the meantime, maybe somebody will have an idea? I strongly suspect wxGTK but will see.

Cheers,
Mikey

PS. Before I upgraded to amule 2.0.0 I was running 2.0.0 RC8, with wxGTK 2.4.2, no problems there, only occasional crash of amule (apparently known problem fixed before 2.0.0 release, as I've read somewhere on this forum).

if you have verbose enabled in your prefs, disable it.. it's the most posted "amule kills my CPU" reasons

Very quickly, here is a backtrace after attaching with gdb. No bt full because there are no symbols. Have no time to analyze it yet. Gotta go.

tvferret,

I just answered the part regarding --enable-maintainer-mode :)

Btw, is this a backtrace of when the program is locked? I see nothing wrong there. The only wrong thing is that I see no debug information. Are you sure you used --enable-debug? Maybe you are running another executable of aMule that is first in the path?

Cheers!

pheonix,

The backtrace is from the program when it's locked. I attached with gdb, it seems to be stuck in _dl_sysinfo_int80(). Have no idea why though. And I haven't had a chance to compile debug version yet (need to recompile wxGTK as well). Most likely will do it over weekend.

Hello people

Any news yet about what could be the reason?
I am using Debian Sarge, and i installed amule from an apt-repository i found at apt-get.org, using these sources.list lines:

deb http://www.vollstreckernet.de/debian testing amule
deb http://www.vollstreckernet.de/debian testing wx
deb-src http://www.vollstreckernet.de/debian testing amule

I installed the packages
amule-common_2.0.0-re1+CVS20050511-1_i386.deb
amule_2.0.0-rel+CVS20050511-1_i386.deb
amuleweb_2.0.0-rel+CVS20050511-1_i386.deb

it installed some wx-packages cause of dependencies, dpkg -l *wx* | grep ii shows me the following wx-packages installed:

libwxbase2.4 - Version 2.4.2.6.1
libwxgtk2.4 - Version 2.4.2.6.1
libwxgtk2.5.3 - Version 2.5.3.2-2

I have the same problem as described here, first time i started amule it run fine for about 5 to 7 hours. Then when I came back it was "hanging", cpu-usage was at 100%, amule was consuming most of it.
I killed amule then and restarted it, after about 1 hour it hang again.
In the console I didn't see any messages about a problem, the last lines on the console were things like

Empty dir /somedir
Empty dir /someotherdir

Just thought i'll report it here, so you know you are not the only one with that problem.
If I got some time tomorrow i'll compile wx and the source myself.. but I hoped being able to avoid that.

greetings
Elias

Edit:
I forgot to tell that simply adding the lines

deb http://www.vollstreckernet.de/debian testing amule
deb http://www.vollstreckernet.de/debian testing wx

and doing an
apt-get update
apt-get install amule
(as described at http://www.amule.org/wiki/index.php/HowTo_Compile_In_Debian under Section 'Are you sure you want to compile?')
 did not work on my system, I run into an

Package amule is not available, but is reffered to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source.
E: Package amule has no installation candidate

so i just downloaded the packages mentioned above and installed them with dpkg.
