[boost] MAP and Vector clear is not releasing memory

26 Feb 2025

      Hi,

map and vector stored in shared memory using boost apis and called clear to
release memory. when i insert same key i see old data present. want to
check using boost map.clear or vec.clear is not removing content.

Example:

pod_list[] (vector contains following 3 members)
pod_info  {

                pod_id
                du_map.
               cell_map.

             }

Step 1: Added elements

Step 2: pod_list.clear();

Step 3:  observed no elements in pod_list empty

Step 4:  Added only key

pod_info.pod_id = 1;

pod_list.insert(pod_info);

Step 5: i see old content map to this pod_id. after this expecting
du_map.size and cell_map size is empty. but du_map,cell_map content is same
as before clear

want to check is clear will not remove memory? is any other best way to
clean this vector.
