memory leak in function "get_host_availability_data" |

Array "ha" is a static array, which keeps its value between function invocations and is declared as follows: static zbx_host_availability_t *ha = NULL; static int ha_alloc = 0, ha_num = 0; Error messages are strdup()-ed using ZBX_STRDUP(), which frees the old string before allocating a new one. There is no need to free the "ha" array and its contents upon function exit - it will be reused in the next function call. |
