Len
shows the length of memory deallocation in bytes.
From
shows the type of memory organization to which memory has been deallocated,
where LIST and POOL are the possible values.
Addr
shows the buffer address where memory has been deallocated.
Count In List
is the number of preallocated control blocks left in the list. Some control blocks may
be preallocated by the traced process so that fast allocation and deallocation may
occur. These preallocated control blocks are placed on lists. Control blocks allocated
from a list will be deallocated back to the same list.
Count From Pool
shows how many control blocks have been deallocated to the memory pool.
Request In
This trace record is for Compaq internal use and shows a request received from another
process.
Receive Tag
shows the message tag of the associated request message.
Sync ID
shows the sync ID of the associated request message. The file-system generates sync
IDs. Sync IDs prevent duplication of requests in I/O operations. For further
information on them, see the Guardian 90 Operating System Programmer’s Guide.
