Perhaps someone can offer some clues to the problem. A user is experiencing a
hang during a Sleep(5) function! It’s Win7 64-bit Hyperthreaded Intel 4 core
CPU.
With MadExcept, it is showing the following…
exception message : The application seems to be frozen.
main thread ($9f4):
771dfd6a ntdll.dll NtDelayExecution
75ce31b5 KERNELBASE.dll SleepEx
75ce3a86 KERNELBASE.dll Sleep
005dc66b SPLStudio.exe StudioMain 6808 +9 LoopSleep
3 known threads are sitting at a Synchronize/NtWaitForSingleObject waiting for
the current procedure in the main form to finish, which is sitting at Sleep(5).
I would expect that.
Another thread is also sitting at NtWaitForSingleObject but it doesn’t say what
the thread class name is so not sure what it is.
Another unknown thread is at NtWaitForMultipleObjects.
And another unknown thread is at NtWaitForWorkViaWorkerFactory.
I know about the 3 threads waiting at Synchronize, but they shouldn’t be a
problem.
What can cause a Sleep(5) to hang for over 90 seconds?
I can send the full bugreport.txt file if useful.
Thanks,
Ross.
Hi Ross,
Bugreport.txt will be usefull plus a short desc as to why you sleeping and what
the app is waiting for?
Cheers,
Pieter
