I have an application which is networked it will basiclly work as a server
where clients connect and then be controlled by the server after they have
connected. Every client that connects the Server loads an Icon for that
Client.
Here comes a problem when the there are as many icons or connected clients
as 15 + the application crushes, Living behind lots of
-----backtraces------- which i have no idea about.
Something even more confusing is that some times it will crush when there
are few client or icons as 8 and sometimes it crushes when there are as many
client or icons as possible like 30+. I can't seem to understand this
indifferences.
This only happens when i ENABLE the codes that load the icons when client
connection are recieved. But when i don't enable to codes Loading the client
icons when connected the application does not crush.
In every crush i rcieved different error messages
HERE ARE SOME OF THE SNAPSHOTS I TOOK IN DIFFERENT STAGES OF THE CRUSH.
