Hi all.

I have weired problem with signals sending between threads.

1) I have a thread. In the run() function I create a signals reciever object and connect signals to it:
Qt Code: 
  1. void LogServiceThread::run()
  2. {
  3.     // Create worker.
  4.     try
  5.     {
  6.         m_impl->m_worker.reset(new LogWorker(m_impl->m_fileName));
  7.     }
  8.     catch (...)
  9.     {
  10.         // Ignore all exceptions. If something gone wrong with worker - continue work silently.
  11.     }
  12.     // Connect signals to worker.
  13.     if (!m_impl->m_worker.isNull())
  14.     {
  15.         connect(this, SIGNAL(writeAsynchSignal(QString)), m_impl->m_worker.data(), SLOT(writeMessage(QString)), Qt::QueuedConnection);
  16.     }
  17.     // Run event loop.
  18.     exec();
  19. }
To copy to clipboard, switch view to plain text mode 
2) Now I try to send som signals to it by main thread
Qt Code: 
  1. void LogServiceThread::writeAsynch(const QString & string)
  2. {
  3.     emit writeAsynchSignal(string);
  4. }
To copy to clipboard, switch view to plain text mode 

So basically, this is an asynchronous thread safe logger. And I got weired problem: sometimes SOME log messages are missing. Some signals are emited but never come to slot! Sometimes I got all messages during run, some times only few.

What I am missing?

Thanks.
