--- Comment #3 from Scott Severtson <scott@severtson.us>  2009-02-10 12:39:25 PST ---
A similar but not identical case:

Solaris 10 Generic_138889-03 on x86 (occurs on both 32/64 bit hardware)
Tomcat 6.0.18
Tomcat Native 1.1.16
APR 1.3.3
Apache 2.2.11
Using mod_proxy_ajp and AjpAprProtocol

All tools compiled with GCC 3.4.3

mod_proxy_ajp times out waiting for tomcat to respond with:
The timeout specified has expired: ajp_ilink_receive() can't receive header

This occurs intermittently while loading a JSP consisting of:
 <%=System.currentTimeMillis()%>

I've proxied the AJP port, and can see the request being issued from
mod_proxy_ajp, but no response is generated. I've added an AccessLogValve, but
the requests that timeout are not logged.

Switching from AjpAprProtocol to AjpProtocol works around the problem, as
Tomcat Native is no longer in use.

Sounds like polling is broken on Solaris. 

I am available to assist anyone with investigation/debugging - please let me
know how I can help.
