[QUOTE="Oxan, post: 737708, member: 97484"] I'm having some problems under high load (multiple concurrent queries). After waiting a few minutes everything seems to work fine again. It seems to be caused by an exception in the GetChannelBasicById function (but the channel does exist, as the same code works later). Is there some way I can debug this kind of errors?
