Hi all, debugging my app I have found it sometimes takes the CPU at 100% for several seconds, and of course for those period the application become a bit unresponsive, even when apparently there is not a lot of activity to do, if I know well my code ;-)

Looking at a strace I can see thousands of error like the following while the CPU gets that busy:

read(6, 0x64ff74, 4096) = -1 EAGAIN (Resource temporarily unavailable)

Same messages are thrown also when I move my mouse over the application window, whatever it is. It might be more related to the OS, but does anyone have a hint? Are these messages significant anyhow, as they are wherever with any app ( I run Linux/KDE)?

Is it maybe the library? I am running Qt libraries 4.7.4

Thanks.
