Hello all,
After many days of work, and docs read I have manage to get it work. Is
a apache 2.2.10 compiled from source on a Centos 5 64b architecture as a
reverse proxy. As a MPM I use prefork.
There are still minor problems like disk_cache but but nothing to worry
. And when all the things seems to work , I start to see in my error log
messages like :

..............
Or:
*** glibc detected *** /usr/local/apache2/bin/httpd: double free or
corruption (!prev): 0x0000000012bba950 ***
followed by the same dump
After this the apache crash. Before this to happen there is nothing
strange to see on the system like heavy load or huge number of requests.
Have anybody see something similar?
Thanks
alex
