:vxdiag_checkstack
Use the :vxdiag_checkstack command to display a summary of the stack activity
for each access point task. A portion of the task stack might look like this
example:
NAME ENTRY TID SIZE CUR HIGH MARGIN
------------ ------------ -------- ----- ----- ----- ------
tExcTask 0x00001a1fd0 fd4e80 7984 224 960 7024
tSysIntegrit 0x000001b188 a3b1c0 16368 720 1176 15192
tLogEventMgr 0x00000fb0ac fd22d8 16368 2136 3616 12752
tShell 0x0000041da8 a2eb78 19320 640 2712 16608
tTelnetd 0x000002e220 a32d90 16368 376 1472 14896
tTelnetOutTa 0x000002e7fc 993da0 16368 720 1800 14568
tTelnetInTas 0x000002e858 98fb88 16368 1416 2376 13992
These are the descriptions of the information in each column:
• Name—name of the task
• Entry—entry point; the top-level function of the task
• TID—task identifier; the task control block
• Size—stack size in bytes
• CUR—current number of bytes of stack in use
• High—highest number of bytes of stack which have been in use
• Margin—the difference between the stack size and the highest number of
bytes which have been in use
Follow the steps in the “Entering Diagnostic Commands” section on page 9-20 to
