 Yep, that's not correct. If you take a look at ct_shm.inc:

class CT_Shm {
        ##
        ## Define these parameters by overwriting or by
        ## deriving your own class from it (recommened)
        ##
...

 The class that's derived from it is in local.inc:

class HordeCT extends CT_Shm {
  var $max_sessions   = 500;               // number of maximum sessions
  var $shm_key        = 0x123754;          // unique shm identifier
  var $shm_size       = 64000;             // size of segment
}

 I had the very same problem (on Solaris), and I upped _this_ version
 of $shm_size to 128000. Case closed :-)
