[opyrus]

in my log files zone errors are no book to send and a null object was passed to client::attack() for evaluation there was also a cupple handlepacket() opcode error: unexpected packet during client_connecting: opcode:OP_bazaarsearch & OP_unknown & OP_inspectanswer also inventory::_putitem: invalid slot_id. one if not all of the errors must be making it crash. the server is more then able to handle the load usualy use low to no cpu and like 1gig ram of 2gig+ 10 gig pagefile.
