[users@httpd] AJP and 500/503 error

Hi guys.

I'm experiencing an issue with Apache 2.2.11 on Solaris 10 with
mod_proxy to communicate with a JBoss AS 4.2.3. When I try to reach
the webpage hosted on JBoss trough Apache (in a reverse proxy
configuration), I receive a 500, or sometimes 503 HTTP error. The
Apache error log says:

[Tue Jul 27 19:17:05 2010] [error] ajp_read_header: ajp_ilink_receive failed
[Tue Jul 27 19:17:05 2010] [error] (120006)APR does not understand
this error code: proxy: read response failed from 10.192.236.58:8009
(cr7260ux058)

I've attached a Snoop Capture File (CAP), Wireshark readable, of this
transaction. I can see a GET from Apache, after a keepalive, after a
TCP FIN. I suspect of timeout. Can somebody confirm it? Someone
already had this issue?

My mod_proxy configuration is:

<Proxy balancer://http-wcm>
    BalancerMember http://webloadbalancer.jboss.caixa:5510 keepalive=on
</Proxy>

Att,
