Application Freezing Problem
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..
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?
with a debugger attached you can press the pause button and check the callstack.
This should give some hints which method causes the freezing.
And you cannot log anything to file about what is happening ?
