Memory Buffer Allocation Records
nnnnaaaa
indicates the internal ID of the socket for which the new control block could not be
created.
Creating New TCPCB Record
The creating new TCPCB record is generated each time a new control block is created
for a TCP socket.
nnnnaaaa
indicates the internal ID of the socket for which the new control block is being
created.
Reserve Space Record
The reserve space record is generated each time a socket structure needs to be
created for an incoming TCP connection.
nnnnaaaa
indicates the internal ID of the socket being reserved.
Memory Buffer Allocation Records
This subsection describes the formatted trace records displayed when the MBUF
keyword is specified for the PTrace SELECT command. Note that there is only one
memory buffer allocation record and that each memory buffer allocation record in the
trace file is preceded by a header containing the record-type code 2.
Memory Buffer Allocation Record
The memory buffer allocation record is generated each time the NonStop TCP/IP
process attempts to allocate memory buffers (MBUFs). Note that this record is
generated even when the allocation attempt fails.
