Maximum number of clients reached

Chris CCF

I would like to know how could I increase this number limit? My application would turn on many QWidget by show(). After tens of QWidget shown, a warning "Maximum number of clients reached" appeared at my terminal and program stopped running.

Hi and welcome to devnet,

How many widgets are you generating exactly ?

Chris CCF

@SGaist

After 52 individual QWidgets (widget form) show() and then the terminal complain about "Maximum number of clients reached".

SGaist

For how long do you have your system running ?

See this thread for some hints.

Seems like this is the problem of gtk...

Hi
Its more like an X server issue i think
https://bbs.archlinux.org/viewtopic.php?id=188052
" MAXCLIENTS variable in xorg-server sources from 256 to 512."

So i do wonder if you get only 51 ?

@mrjj
Do you think there is any solution? I think this is quite hard to tackle. Right?

Hi
Seems people just recompile their xorg.

Also you might be able to just upgrade xorg?
