show memory debug leaks
To display detected memory leaks, use the show memory debug leaks command in privileged EXEC
mode.
show memory debug leaks [chunks | largest | lowmem | summary]
Syntax Description
Command Modes Privileged EXEC
Command History
Usage Guidelines If no optional keywords are specified, the show memory debug leaks command invokes normal mode
memory leak detection and does not look for memory leaks in chunks.
The show memory debug leaks chunks command invokes normal mode memory leak detection and
looks for leaks in chunks as well.
The show memory debug leaks largest command displays the top ten leaking allocator_pcs and the
total amount of memory that they have leaked. Additionally, each time this command is invoked it
remembers the previous invocation's report and compares it to the current invocation's report. If there
are new entries in the current report they are tagged as “inconclusive.” If the same entry appears in the
previous invocation's report and the current invocation's report, the inconclusive tag is not added. It
would be beneficial to run memory leak detection more than once and to consider only the consistently
reported leaks.
The show memory debug leaks lowmem command forces memory leak detection to work in low
memory mode. The amount of time taken for analysis is considerably greater than that of normal mode.
The output for this command is similar to the show memory debug leaks command. You can use this
command when you already know that normal mode memory leak detection will fail (perhaps by an
unsuccessful previous attempt to invoke normal mode memory leak detection).
The show memory debug leaks summary command reports memory leaks based on allocator_pc and
then on the size of the block.
chunks (Optional) Displays the memory leaks in chunks.
largest (Optional) Displays the top ten leaking allocator_pcs based on size, and the
total amount of memory they have leaked.
lowmem (Optional) Forces the memory leak detector to work in low memory mode,
making no memory allocations.
summary (Optional) Reports summarized memory leaks based on allocator_pc and
size of the memory block.
