NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for SYS$PUDRIVER.EXE on OpenVMS Alpha V7.0. This
kit addresses the following problems:
o A system crash occurs when an attempt is made to place a CDRP
into a wait state and the CDRP is already in another incompatible
wait state.
The system has no messages available, and some CDRPs have been
placed into the message wait queue. A message response frees a
message which is placed in the response ring. Another message
becomes available and the response ring fills up. A check is
then made for message waiters. A waiter is found and a successful
attempt is made to start it. An attempt is then made to start
the next waiter, but there are no more messages so the system
begins looking for one. When a message is found, a call is
made into the SCS routine to start the first waiter which is the
waiter that originally started the loop. Eventually, a return
is made to the first waiter which was already started in an
inner loop. The system then either waits or starts the waiter
again which causes it to be in two states at the same time.
This problem will only occur with a KCM44 controller because it
issues the system 45 credits which are enough to exhaust the
message queue if a heavy amount of IO is occurring.
INSTALLATION NOTES:
In order for the corrections in this kit to take effect, the system
must be rebooted. If the system is a member of a VMScluster, the
entire cluster should be rebooted.
