How to resolve this issue ?

Most likely you have memory leak in code, find it.

i am using GATT server example as it is .i use it for continuously read response from esp32 .i had gone trough application code and esp-idf components after each ESP_GATTS_READ_EVT i see in function
void btc_gatts_arg_deep_copy(btc_msg_t *msg, void *p_dest, void *p_src) at
case BTC_GATTS_ACT_SEND_RESPONSE: memory allocation for
dst->send_rsp.rsp = (esp_gatt_rsp_t *) osi_malloc(sizeof(esp_gatt_rsp_t));

vary for each ESP_GATTS_READ_EVT and its gets incremented and after some time its gets beyond the arg address form the
bt_status_t btc_transfer_context(btc_msg_t *msg, void *arg, int arg_len, btc_arg_deep_copy_t copy_func)

i had try out to do osi_free (dst->send_rsp.rsp ) but it not work rather it crashes often .please help me out from it any one has solution on it
