Hello,
I'm experiencing crashes with an application that i have developed in
Cocoa. Everything seems to run fine, but the application crashes after
22 minutes on every run.
The application is relatively straight-forward:
1) Main thread initiates a second thread - all the steps below happen
on this thread
2) Initiates a one-shot NSTimer and adds it to the current run loop
3) The callback of the NSTimer contains an NSTask object, that pings
another host
- If the host does not respond, step 2 is performed again
4) If the host responds, a synchronization method is run, and the loop
starts again at step 2
I am running with garbage collection enabled, so I do not reckon that
it is a memory issue. The crash seems to happen shortly afther the
NSTimer callback has been executed, and I am left with little debug
information.
I am hoping that someone here has experienced something similar, and
can help me overcome the issue. Thank you very much.
Please let me know if you would like to see any source code.
Regards, Logan Raarup
