Let me give you a background of my application. it is designed in qt c++ for Mac OS. Qt starts server at localhost 1234. My front end client connects to this server and file transfer takes place between both. This file transfer is basically tranfer of resources.
Now somehow my front end client is getting killed and regenerated with new pid. On looking at system.log in MAC OS I see that the process is getting killed by SIGKILL sent by launchhd. I am unable to debug why this front end client is suddenly getting killed and getting regenerated with a new pid. The application turns white i.e front end turns white and I am unable to proceed in application.
Help me to maybe give some idea to handle this situation. -
