This is not a remote DOS. It is a queue file corruption problem.
There is one place where the queue manager will get a 'transport' name
from a queue file, and that is a record with a content filter value.
The OP has shared the queue file off list. The file is corrupted,
and the cause for that corruption is yet to be determined.
The queue file contains a record with type 'L' (content filter),
length 2048, and value 'fwZ+GX2pP7y/mKTz0/vD8xX7o....'. That explains
why qmgr tried to connect to 'private/fwZ+GX2pP7y/mKTz0/vD8xX7o.....'.

That leaves the cause for file corruption to be determined.
