ERROR BlockingIOCometSupport:192 - Unable to resume suspende

metinbaris · 26 Dec 2013, 14:44

Hi to all,

I am using Primefaces 3.5 with Atmosphere 1.0.1, on Tomcat 7.

In web.xml, I have

<context-param>
    <param-name>primefaces.PUSH_SERVER_URL</param-name>
    <param-value>http://localhost:8083</param-value>
  </context-param>
  <servlet>
    <servlet-name>Push Servlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>Push Servlet</servlet-name>
    <url-pattern>/primepush/*</url-pattern>
  </servlet-mapping>

In my application, in every 2 minutes, there are ~50 pushes from the server. Pushes to clients are sometimes successfully, but sometimes I come accross the following error;

ERROR BlockingIOCometSupport:192 - Unable to resume suspended connection.

What can be the problem?

Thanks in advance,

Metin

1. It may be best to use at least Atmosphere 1.0.12 with PrimeFaces 3.5
2. what version of tomcat 7 are you using? tomcat 7.0.47 or an earlier/older release?

are you using default BIO connector? you may want to use tomcat's NIO connector (see below).

Code: Select all

    <Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" connectionTimeout="20000" acceptorThreadCount="2"
               redirectPort="8443" socket.directBuffer="false"/>

also, i recommend that you try atmosphere 2.0.3 or atmosphere 2.1.0-RC2 and PrimeFaces Elite 4.0.4 with the following web.xml:

Code: Select all

    <servlet>
        <servlet-name>Push Servlet</servlet-name>
        <servlet-class>org.primefaces.push.PushServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        <init-param>
            <param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>
            <param-value>org.atmosphere.cache.UUIDBroadcasterCache</param-value>
        </init-param>
        <async-supported>true</async-supported>
    </servlet>
    <servlet-mapping>
        <servlet-name>Push Servlet</servlet-name>
        <url-pattern>/primepush/*</url-pattern>
    </servlet-mapping>

I will try your suggestions and trace the progress.
Thank you very much.

I had put trace logs of Atmosphere framework in the application. The application was working successfuly for months, but suddenly websocket was closed and push is not working now. Below are the Atmosphere trace logs about the errors. I searched for the solution on internet with no success.

reply with the following (after Dec 30, 2013)
* your PrimeFaces Push xhtml
* your java bean code
* your web.xml (entire web.xml)
* your dependencies (pom.xml), so we can see what version of PrimeFaces, Atmosphere, etc... that you are using

and then reply with what changed 'above' to possibly cause PrimeFaces Push to not work on May 5, 2014.

I applied NIO Connector with the parameters you supplied, updated Primefaces to V3.5 and Atmosphere to V1.0.12 but I got the same push problem after months.
(I tried to update PF to V4 but I got many errors, so I moved back to PF V3.5)

As applying your suggestions, I put also trace logs for Atmosphere framework in December. I thought that the problem was solved because the push was working for a long period. But in May, push was suspended. So the same problem still exists. And I posted with Atmosphere logs.

The codes for push are below.

the following (multiple p:socket's) is not/never recommended. you 'really' should avoid multiple p:socket's on one page, have one channel, and in your handleMessage, read the messages pushed from the server, and update your page, accordingly, per message pushed from server. Look at PrimeFaces Push showcase - Chat app, and look for the p:remoteCommand, etc...

Code: Select all

      <p:socket onMessage="handleMessage" channel="/counter" >      
            <p:ajax onstart="disableBlock();" oncomplete="enableBlock();" update="frmR:feedbackGrid" />
            </p:socket>
            <p:socket onMessage="handleFrequency" channel="/frequency" />
            
            <p:socket onMessage="pushDevices" channel="/gpscounter" onstart="disableBlock();" oncomplete="enableBlock();" />
            
            <p:socket onMessage="handleKKCStatus" channel="/kkcscounter" onstart="disableBlock();" oncomplete="enableBlock();" />

what browser and tomcat version worked well together between December and May?

atmosphere 1.0.12 and primefaces 3.5 is quite old. would be nice if you can migrate your app to primefaces 5.0 and use atmosphere 2.1.3 (but remember primefaces push is changed in primefaces 5.0, pushcontext is deprecated,and you have to use eventbus, etc...).

if/when you migrate to primefaces 5.0 and use atmosphere 2.1.3, my recommendation is to change the following:

Code: Select all

  <servlet>
    <servlet-name>Push Servlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>Push Servlet</servlet-name>
    <url-pattern>/primepush/*</url-pattern>
  </servlet-mapping>

to this below,

Code: Select all

    <servlet>
        <servlet-name>Push Servlet</servlet-name>
        <servlet-class>org.primefaces.push.PushServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        <init-param>
            <param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>
            <param-value>org.atmosphere.cache.UUIDBroadcasterCache</param-value>
        </init-param>
        <async-supported>true</async-supported>
    </servlet>
    <servlet-mapping>
        <servlet-name>Push Servlet</servlet-name>
        <url-pattern>/primepush/*</url-pattern>
    </servlet-mapping>

where you will need this (for servlet 3.0 web.xml and atmosphere 2.1.3)

Code: Select all

        <async-supported>true</async-supported>

and Jeanfrancois recommends this

Code: Select all

        <init-param>
            <param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>
            <param-value>org.atmosphere.cache.UUIDBroadcasterCache</param-value>
        </init-param>

Hello Howard,

We've migrated to PF 5.0 and Atmosphere 2.1.3, we've also made changes you suggested. However the problem still exists. Everything works for a while(approximately 1 week long), then push stops working. The following error occurs continuously on server side and the application cannot properly work. This forces me to shutdown the server:

    </servlet>

	<servlet-mapping>
		<servlet-name>Push Servlet</servlet-name>
		<url-pattern>/primepush/*</url-pattern>
	</servlet-mapping>

Since async support is enabled, I do not understand why it throws not supported exceptions after working for a period of time.

Thanks in advance.

what happens when you migrate to PrimeFaces 5.1 and Atmosphere 2.2.5?

metinbaris · 14 Feb 2015, 18:40

I think this issue is not about the version, since I tried PF 3.5, PF 4 and PF 5 for a long time. We used all of these PF versions in our project for more then 1 year and the same problem occured with all versions: Push works for a period of time, and then it stops after throwing "java.lang.IllegalStateException: Not supported" exceptions.

I also tried to upgrade PF to 5.1, but our charts didn't work after migration. Since I can't deploy in production right now, I can't reproduce the error.
Is there a limitation on push thread counts or any other configuration?

Thanks in advance.
