Collect Memory Leak Information

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

|

FRR processes have the capabilities to report remaining memory allocations upon
|
||||
exit. To enable the reporting of the memory, define an environment variable
|
||||
FRR processes can report unfreed memory allocations upon exit. To
|
||||
enable the reporting of memory leaks, define an environment variable
|
||||
``TOPOTESTS_CHECK_MEMLEAK`` with the file prefix, i.e.::
|
||||
|
||||
export TOPOTESTS_CHECK_MEMLEAK="/home/mydir/memleak_"
|
||||
|
||||
This will enable the check and output to console and the writing of the

:file:`/home/mydir/memcheck_test_bgp_multiview_topo1.txt` in case of a memory
