Hi,
I am sending string in a queue at that time esp32 gets reset.
if(xQueueSend( xQueue, ( void * ) &single_tag, ( portTickType ) 0 )==errQUEUE_FULL)
{
ESP_LOGI("Queue","Queue is full..");
}

error:

C:/esp32/esp-idf/components/freertos/queue.c:718 (xQueueGenericSend)- assert failed!
abort() was called at PC 0x4008c717 on core 0

Not getting what is the problem..please help me out for the problem..

This can be few things. Are you initializing xQueue before you use it? You want to pass stringand you dereferencing it with &, but char[] is equivalent to char* and is pointer without dereferencing. This is wrong, unless you want to pass pointer to pointer.

Chegewara is right on the money for the first option: The assert there checks if the xQueue (the first parameter to xQueueGenericSend) is NULL. That seems to be the case here; either you have not initialized xQueue with xQueueCreate, or you did but that call failed because of low memory.

Problem is solved.
actually I have used
xQueue = xQueueCreate( 500,1024);
now changed to..
xQueue = xQueueCreate( 500,8);
