  .
  CSQ2005I with FEEDBACK 293, MQFB_DATA_LENGTH_TOO_BIG, when an
  IMS reply message longer than 32764 is received by the IMS
  Bridge (IMS OTMA supports up to 32767 so there is no reason why
  the MQ IMS Bridge should not do the same).
  

Local fix

• Reducing the size of the message to be no longer than 32764 will
  prevent the problem from occurring.

  When processing an IMS message, the queue manager checks that
  the length in the LL bytes for each segment is not more than
  32764 bytes, however OTMA can support segments up to 32767
  bytes.
  

Problem conclusion

• The MQ IMS bridge and MQ conversion routines are updated to
  handle IMS messages containing segments of up to 32767 bytes.
