IEE286I

Explanation
The buffer for the following messages is filled
and cannot be expanded: Branch-entry write to operator (WTO)
Branch-entry write to operator with reply (WTOR)
Delete operator messages (DOM)

System action
Until space becomes available: during nucleus initialization program (NIP), the system sends
all messages to the console, but not to the hardcopy log
after NIP, the system does not send branch-entry messages to any
console or to the hardcopy log
the system sends synchronous messages to the console, but not
to the hardcopy log.

The system may reject some messages and DOMs (delete operator
message). Callers of branch-entry WTO, WTOR, and DOM will  receive
a return code '40'x. 
When space becomes available, message
IEE287I will be issued with information about lost messages.
The
system may delete some messages.  Callers of branch-entry WTO, WTOR,
and DOM will receive a return code. When space is regained, the system
issues message IEE287I.

Operator response
Because DOMs might have been lost, examine
the output of a DISPLAY R command to determine if there are any outstanding
messages.  If not, remove the DOMs with the CONTROL C command. 
If
IEE286I remains outstanding without a corresponding IEE287I message
and/or repeated thrashing of IEE286I and IEE287I occur, report the
problem to your System Programmer.
