ECO KIT SUMMARY:

An ECO (patch) kit exists for DECmessageQ for OpenVMS VAX  V2.0.
This kit addresses the following problems in addition to those already
addressed in ECO 1.

      o     Corrected a problem with sending a message to queue
            999 generating PAMS__BADPARAM

      o     More than 100 Avail/Unavail registrations for a remote
            group causes SBS Server crash

      o     Corrects five problems with the MRS Server:
            1) Dynamic expansion of internal data structures
               could cause a server crash
            2) Increased number of open SAF files to 255
            3) SAF_FILES quota now will limit total number of
               SAF files
            4) TARGET_PRESENTATION is now uniformly applied
            5) Loss of FIFO when target queue is full

      o     Corrects three problems:
            1) Avail/Unavail services causes initialization to
               enter an endless loop
            2) COM Server logging "Duplicate Queue Notification"
               events
            3) LIST_ALL_Q_RESP message does not return tag number

      o     Corrected problem with redelivery of unconfirmed
            recoverable messages to an MRQ after a client abort.

      o     Corrected a problem with some cross-group messages
            remaining in the DQF and are not removed until MRS is
            restarted.  Also, corrected a problem with data
            structure expansion in the MRS Server.

      o     Corrected a problem with the SBS Server generating false
            sequence gap notification events.

      o     Corrected a problem with the MRS Server where memory
            writes occurred beyond an array boundary.  Also,
            corrected a problem with the MRS Server attempting to
            send the same message twice to an MRQ.

      o     Corrected a problem with buffer pool free counts
            exceeding total buffer counts.

      o     Corrected a problem with the SBS Server not handling
            soft controller errors from optimized Ethernet
                      broadcasting.

      o     Corrected a problem with losing PAMS timers with
            negative timer ID's.  This caused the MRS Server to
            lose it's retry timer.

      o     Corrected two problems with the COM Server's switching
            DECnet connections.  The first logs "Detected out of
            order write QIO completion" messages and the second,
            the prior link's DECnet I/O channels are not freed.

      o     Corrected a problem with the handling of negative
            sequence numbers that were passed to the MRS Server by
            PAMS_CONFIRM_MSG.  Prior to this correction, a message
            sequence number with the sign bit on in the high order
            longword could cause the MRS Server to either abort
            with an access violation or to loop indefinitely.



INSTALLATION NOTES:
