Hi Oswald, thanks for your reply . I am trying to track down what is this process could be . is there any way you recommend I approach the problem ?
when breaking in those "hangs" I consistently fall in a select call : see below the stack trace from qt-creator . 0 select /lib64/libc.so.6 0 0x00000038abccc4c2 1 QProcessManager::run qprocess_unix.cpp 245 0x00002b6eb12f93c4 2 QThreadPrivate::start qthread_unix.cpp 244 0x00002b6eb121f035 3 start_thread /lib64/libpthread.so.0 0 0x00000038ac806367 4 clone /lib64/libc.so.6 0 0x00000038abcd2f7d I am not sure how to tell what process is running that is hanging the system ? any hint ?
