HI -  
I'm not sure if this is totally related to your problem, but I have similar issues.  If there's a firewall in between your apache and application server, then the solution that worked for me was keepalive On.

The default Linux keepalive settings will need to be modified to match those of the allowable idle connection time out on the firewall.

LINUX DEFAULTS:
# cat /proc/sys/net/ipv4/tcp_keepalive_time
7200
# cat /proc/sys/net/ipv4/tcp_keepalive_intvl
75
# cat /proc/sys/net/ipv4/tcp_keepalive_probes
9

Apache settings:
ProxyPass ....  keepalive=On 

For additional info, see http://libkeepalive.sourceforge.net/docs/TCP-Keepalive-HOWTO
