Problem with mod_proxy_ajp re buffer size

[Kallisti]

Hi!

I have been trying to get Zimbra working together with another webserver, using these wiki-instructions as a basis. I have created a virtual host (see below) in apache for all my Zimbra activities routing everything going to that host to the ajp-interface. Both the webmail and WebDAV seems to work perfectly fine. My problems come when trying to access ZimbraAdmin and ZimbraDesktop through the virtual host and ajp.

It seems to be that ajp doesn't like big responses, my logs are full of

[Fri Apr 11 16:20:01 2008] [error] ajp_read_header: ajp_ilink_receive failed
[Fri Apr 11 16:20:01 2008] [error] (120007)APR does not understand this error code: proxy: send body failed to 127.0.0.1:8009 (localhost)

The result for /zimbraAdmin is that the POST to /service/admin/soap/GetInfoRequest receives an error from apache apparently from port 80 (everything is supposed to be https). I see the error message using FireBug.

When trying to access zimbra using ZimbraDesktop it's also unable to finish the process and the logs are the same. Anyone got a clue? Is there a way to increase the buffer size for ajp or is that just a symptom of something else?

Zimbra was configured for https and ajp only. The proxy was on another host (also RHEL5.1). User access to that proxy was also https.

[edit] Is it normal that jetty reports the requests as http/1.1?[/edit]

Same problem here. When i use the Jetty HTTP connector it al works fine. But now I added a AJP connector like
Zimbra with Apache using mod jk - mod proxy - mod proxy ajp - Zimbra :: Wiki

But now i get a 503 exception

1. While opening some specifik HTML email messages i receive the following message:

code: CSFE_SVC_ERROR
method: GetMsgRequest
detail: HTTP response status 503

2. When i press the send/receive email button i also get:
code: CSFE_SVC_ERROR
method: SearchRequest
detail: HTTP response status 503

I added some connector parameters to the AJP connection like:

PHP Code:

    <Call name="addConnector">
      <Arg>
        <New id="ajp" class="org.mortbay.jetty.ajp.Ajp13SocketConnector">
          <Set name="port">8009</Set>
          <Set name="maxIdleTime">30000</Set>
          <Set name="lowResourceMaxIdleTime">1000</Set>
          <Set name="Acceptors">2</Set>
        </New>
      </Arg>
    </Call> 


But i still get the errors... For more connector arguments like buffers etc. take a look in de JavaDoc of de Ajp13SocketConnector
Ajp13SocketConnector (Jetty Server Project 6.1-SNAPSHOT API)


For now i work with mod_proxy over http. Some help from the Zimbra admins on this issue would be very nice.
