"QSocketNotifier: invalid socket 'Write' and type 26, disabling" What generates this?

[MattPhillips]

Anyone have an idea?

You have a pointer where you write beyond the boundaries of the pointer corrupting the heap.

Thanks tbscope. I've found that while I can't get rid of this error entirely, reducing traffic on that socket and putting the body of WriteToLog within a mutex allows me to avoid it, which is good enough for me for now. I don't understand how the problem could continue to exist once I've invoked a mutex (and WriteToLog is the only place where the socket is written to), but oh well...
