This is true for dialog information as well (dlg_var's etc.). Continuous growth in memory at a constant call rate (incoming sip requests) might mean a leak. If you need statistics about the total memory usage you can use `kamctl fifo get_statistics all` and check for the shmem real_used_size and max_used_size fields.
