# API03007: Request Queue Full

## What This Means[​](#what-this-means "Direct link to What This Means")

The POS has too many pending requests waiting to be sent. The internal queue is full and cannot accept more requests until some complete.

## Common Causes[​](#common-causes "Direct link to Common Causes")

* **Slow network** — Requests backing up due to slow connection
* **Server unresponsive** — Server taking too long to respond
* **Rapid actions** — Performing many actions faster than they can process
* **Sync overload** — Large sync operation blocking the queue

## How to Fix[​](#how-to-fix "Direct link to How to Fix")

### 1. Wait for Queue to Clear[​](#1-wait-for-queue-to-clear "Direct link to 1. Wait for Queue to Clear")

Give pending requests time to complete:

* Wait 30-60 seconds
* Watch for sync indicators to complete
* Avoid additional actions until cleared

### 2. Check Network Connection[​](#2-check-network-connection "Direct link to 2. Check Network Connection")

A slow connection causes backup:

* Test your internet speed
* Try a faster connection
* Move closer to WiFi router

### 3. Check Server Response Time[​](#3-check-server-response-time "Direct link to 3. Check Server Response Time")

If the server is slow:

* Test accessing your site in a browser
* Contact hosting if site is slow
* Wait for server load to decrease

### 4. Restart the POS[​](#4-restart-the-pos "Direct link to 4. Restart the POS")

If the queue is stuck:

1. Close the POS application
2. Wait a moment
3. Reopen the POS
4. Pending requests may need to be re-initiated

### 5. Avoid Rapid Actions[​](#5-avoid-rapid-actions "Direct link to 5. Avoid Rapid Actions")

During sync or slow periods:

* Wait for one action to complete before starting another
* Don't repeatedly click buttons
* Be patient with network operations

## Offline Behaviour[​](#offline-behaviour "Direct link to Offline Behaviour")

When the queue fills due to offline conditions:

* The POS will hold pending requests until back online
* You can still browse cached products and customers
* You can start new orders and add items to the cart
* Completing orders requires connectivity to be restored
