running 2 skype instances on ubuntu 13.04 64bit (one gets blocked)...

hi,

i run skype 4.2 on ubuntu 13.04 with 2 accounts.
they're launched with this commands:

Code:

echo user1 pwd1 | LD_PRELOAD=/usr/lib/i386-linux-gnu/mesa/libGL.so.1 skype --pipelogin --dbpath=~/.Skype1 &

echo user2 pwd2 | LD_PRELOAD=/usr/lib/i386-linux-gnu/mesa/libGL.so.1 skype --secondary --pipelogin --dbpath=~/.Skype2 &

the 2 instances run fine for some time (usually a few hours), but then one of them crashes and i have to kill it with:

Code:

killall -s SIGKILL skype

a "plain" killall skype won't be enough...

i tried and start both of them with --secondary option, but the problem still occurs.
i tried and launch them from command line to see if some errore message appears, but it does not...

i noticed that i usually find a crashed instance when i come back after a few hours vacation... please mind my system is set to never sleep or hibernate...

and i also noticed that the crashed instance usually has the "away" icon, while both my skype instances are set to never show me as away...

pid 4097 is blocked right now:

Code:

$ ps aux | grep -E "skype|START" | grep -v "grep"
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
teo       4097  1.5  1.7 549024 138720 ?       Sl   Oct26  13:11 skype --pipelogin --dbpath=~/.Skype1
teo       4849  2.3  1.7 550324 138668 ?       Sl   Oct26  20:35 skype --secondary --pipelogin --dbpath=~/.Skype2

the only weird thing i can say about the output above is that both the instances were launched about at the same time, at 13:11...

so the "survived" instance (4849) has wrong start time. the blocked instance has the proper one...

any hint on how to debug this?

Hi

I think that everybody here will be clueless without some more informations.
Maybe you can keep an eye on
1) what gets written to /var/log/messages (or wherever your "dmesg" output is written) and
2) start the two instances using two separate active terminals which might then show interesting stuff when one of the instance fails like failure messages or something similar?

Cheers

interesting:

Code:

$ echo usr pwd | skype --secondary --pipelogin --dbpath=~/.Skype
Gtk-Message: Failed to load module "overlay-scrollbar"
`menu_proxy_module_load': skype: undefined symbol: menu_proxy_module_load

(skype:6964): Gtk-WARNING **: Failed to load type module: (null)

`menu_proxy_module_load': skype: undefined symbol: menu_proxy_module_load

(skype:6964): Gtk-WARNING **: Failed to load type module: (null)

`menu_proxy_module_load': skype: undefined symbol: menu_proxy_module_load

(skype:6964): Gtk-WARNING **: Failed to load type module: (null)

`menu_proxy_module_load': skype: undefined symbol: menu_proxy_module_load

(skype:6964): Gtk-WARNING **: Failed to load type module: (null)

*** Error in `skype': malloc(): memory corruption (fast): 0xf99d949a ***

i guess skype got blocked when the last line appeared...

So maybe you upgraded your GTK-libraries and they do not provide anymore the functionality needed by Skype?

i don't really know... how can i check this?

By searching for the first error => google for "Gtk-Message: Failed to load module "overlay-scrollbar""

Have a look at this - there are a few workarounds mentioned:

i gave up...
turned out with this code: it simply restarts skype as the log shows it's blocked:

Code:

cd /tmp

while :;do
	echo user pwd | skype --secondary --pipelogin --dbpath=~/.Skype &>skypelog &
	
	sleep 60
	
	while [[ -z $(grep "memory corruption" skypelog) ]]; do
		sleep 120
	done
	
	zenity --question --title="skype is blocked..." --text="kill and relaunch skype?"
	if (( $? < 1 )); then
		killall -s SIGKILL skype
	fi
	
done

thanks for your help...
