Centos 5.8, x86_64, apache 2.2.22, java 1.6.0_32, tomcat 7.0.27, apr
1.4.6 (also happens on another machine with apache 2.2.21 and java
1.6.0_29, rest of the versions are the same)
Connecting apache to tomcat ajp, same machine.

1.2.32 and 1.2.35 work fine.
Tomcat catalina.out and access logs show nothing
Jk log shows:
