Application Freezing Problem
-
Hi All,
I have an application working on LinuxMint 17.3 XFCE with QT5.6.. 10 clients and one PostgreSQL server is running. The App must work 7/24 but sometimes 2-3 times a day application freezes.. I couldn't determine the problem that cousing this..
How can I find a solution to detect the problem to couse this.. This is a real headache for me..
Any help will be very valuable..
Thanks..

Hi
Its hard to guess at.
For hanging I often check
locks/semaphores/ wait states
also loops of all kinds.Do you have idea where in the program it could happen ?
do you have any logging at all? -

@zeroptr
with a debugger attached you can press the pause button and check the callstack.
This should give some hints which method causes the freezing. -
Hi @raven-worx ,
there's no development tools installed on kiosks, should I install Qt deveopment enviroment on them ?
Unfortunately it can freeze any where on the application.. There is no routine that freezes the application..
thanks.. for these rapid help..
