Problem summary

• ****************************************************************
  * USERS AFFECTED: All users configuring a large number of      *

  * PROBLEM DESCRIPTION: CONNECTION LIST LCGN command causes     *
  *                      CCLXOTD daemon to shut down.  Message   *

  * RECOMMENDATION:                                              *
  ****************************************************************
  After adding LUs to some physical lines, CCL and CCLXOTD are
  recycled to pick up the changes.   When the command
  CONNECTION LIST LCGN was subsequently issued, CCLXOTD went
  down.
  
  When a large number of VCs is configured for a port for LCGN
  mode, the communication between cclxotd and cclxotm fails
  when processing the cclxotm command CONNECTION LIST LCGN.
  This is because size of a packet sent by the cclxotd process
  to cclxotm is too large for the receiver to handle.
  

Problem conclusion

• The cclxotd module was modified to send multiple smaller
  monitoring data packets to the cclxotm module rather than one
  large packet.
  

Temporary fix
