Actually my host has just told me that I have a number of "hung semaphores" in my server. And he is relating them to postgresql. I am not surprised, because this is the only utility that has issues. All the rest is working (apache, mysql, exim, etc). Any thoughts on where I should start looking for hung semaphores?
