# Colas de procesos en 4º plano

Los procesos que ejecutamos en [4º plano](/33/velneo-vdevelop/proyectos-objetos-y-editores/de-aplicacion-y-datos/proceso.md#4o-plano) se ejecutan secuencialmente en colas. 

Por defecto, Velneo vServer configura 9 colas, pero es algo que podemos configurar o bien [en el ámbito del sistema operativo](/33/velneo-vserver/instalacion-y-configuracion/parametros-configurables-de-velneo-vserver.md#configurar-el-numero-de-colas-para-procesos-en-4o-plano), o bien [en el arranque](/33/velneo-vserver/instalacion-y-configuracion/parametros-configurables-de-velneo-vserver.md#establecer-el-numero-de-colas-para-procesos-en-4o-plano-queues-x).

Las colas se guardan en disco, esto permite que, por ejemplo, si detenemos el servidor, al iniciarlo se volverán a lanzar los procesos que estaban en cola y aún no habían sido ejecutados.

Se guardan en el directorio de [configuración del servidor](/33/velneo-vserver/instalacion-y-configuracion/estructura-de-directorios.md), dentro de una carpeta llamada Colas. Dentro de esta carpeta habrá una subcarpeta por cola definida (si son 9 colas, habrá 9 subcarpetas).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.velneo.com/33/velneo-vserver/funcionalidades/colas-de-procesos-en-4o-plano.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
