erreur de segmentation: segment fault CCcam

seb007

Hi all, sorry for my english, I speak french.

I have SERVER LINUX UBUNTU 8.04 (hardy) i686 INTEL CORE 2 QUAD 4GO DDRIII but my CCcam2.09.x86 (octal 0755) crash from time to time (maximum 3 days without crash > erreur de segmentation: segment fault :(

Can you HELP ME please???
I must all the time control if my server is RUNNING...

How can I find the solution with this error?

Is There a script to start again automatically CCcam.x86 -d after 5 minutes when my server is stopped (segment fault)?

Do you think is possible that is my connection (Download= 12Mbits/s and Upload= 512Kbits/s)?

Sometimes, my computer makes BIP... and in my terminal I have this: (Is the problem perhaps my graphics card?)

I have too more ILEGAL USERS... :(

Thank you for your assistance

Your graphic card is not the culprit. The reason weird characters appears is that there are some ascii sequences that changes the encoding (often with a bip), and does not come back to the original encoding.

This is a known bug of the terminal :
[Only Registered Users Can See LinksClick Here To Register]

This happens often when you "cat" some binary file.
So the weird characters you see in the logs come probably because the logs have displayed one of this sequences (maybe because there is such a sequence in a username, I don't know) that changes the encoding and produce the beep, so all the alphabetic characters are replaced by others...

For your real problem with the segfaults, gdb could be a great help but alas the binaries of CCcam are stripped, so I am not sure it will give a lot of informations. You can try, however (launch "gdb CCcam.x86", then type "run", then when it segfault, type bt [for backtrace]).

By the way, I can write you a script that will check that CCcam is not segfaulted.

How do you start CCcam. If it is by an init script, I can include the check in the init script. Pm me it and I will edit it with some changes in the coming days.

I have a similar problem, but my error message is

My server (2.0.11) chrashes every morning, and I'm not sure why.
I'm using the following script to check the server:

Quote:

#!/bin/sh
if ps x |grep -v grep |grep -c CCcam >/dev/null
then
echo "CCcam ok"
else
echo "CCcam restarting"
/emu/cccam/CCcam.x86 &
fi

I have named the script check.sh, and I placed it in /emu/script. (Remember to do chmod 755 to be able to run it).

I then added the following to crontab to make it run every minute

Quote:

# CCcam check
*/1 * * * * /emu/script/check.sh >> /dev/null 2>&1

Not a good solution though, just a workaround to automatically check and restart the CCcam server if there is a problem.
