aMule crashes after light gone down
« on: November 18, 2005, 12:07:57 PM »
Hello, I'm an aMule user from 2 moths, using Slackware 10.2 (kernel 2.6.13.2).

Two days ago I had my pc running amule for 12 hours when the light went down!
When I rebooted, fsck checked my ext2 filesystems (hda3 and hdd1) fixing any problem.
Then I logged in as "giobik" (this is the user I use for amule) and started amule. I could only see the window for few seconds! On the other hand, when I login as root amule works properly!
OK, I know, if I had an UPS everything would be ok!

Here is the output message when I start amule from the console as giobik:

giobik@spudhead:~$ amule

giobik,

Are you sure you followed the instructions properly? Did you compile aMule with debug information? Does not seem to be from the output you show. Remember to

$ ./configure --enable-debug --disable-optimize

On the other hand, if you did that, the only explanation I can see is that after the power failure, one of your wx-libraries has been corrupted, so maybe it is a good idea to re-install them.

Cheers!

Hello phoenix,

thank you for your interest!

I didn't compile amule with debugging information because I thought that doing this I would have lost any information about the current configuration of amule. I thought that recompiling I would have corrected the errors... Sorry for not have been precise!
Moreover, I didn't compiled amule at all, as I installed it from a .tgz package for Slackware.
What should I do?
May I download the source and recompile it with debugging info in an other directory and launch it as "giobik"?

Bye!

giobik,

Without debug info there is very little we can do to help you.

You can compile aMule in a local directory and run it without interfering with the version you have installed, just don't run both at the same time under the same user.

Here you can find the latest sources:

Everything working!!!

Hello everybody!

Probably I will not tell you anything interesting, but I solved the problem!

After the power failure I created an other user for aMule, because the old giobik user could not start the program... I found my old cryptkey.dat, preferences.dat and clients.met that I had saved some time ago (hoping it would work) and I copied them in the new ~/.aMule directory.

With the new user everything was ok... Initially aMule downloaded pretty slowly for some days, probably because the clients.met file was old... Then I wrote a very simple script to backup the files in ~/.aMule directory every 20 minutes for more security!

Today I had an idea: I copied the ~/.aMule files in the ~/.aMule directory of the "broken" user giobik, in order to see what would happen... When I changed all the permissions and started amule, everything was ok!

So, I realized that aMule continued crashing because the files were broken... That's all!

Thank you for your time!
Happy aMuleing...
