v2.2.14 to 2.0.15 on Solaris and its related configuration changes in httpd.conf, there is
no other changes made. That is why I think there is a problem in Apache v2.2.14.

had two separate virtual servers. At the time, one virtual web server had strictly static
html web pages and served by Apache directly. The other virtual web server uses mod_jk for
the communication between Apache and Tomcat. When the problem happened, clients could access
web server with static web pages no problem. Clients could not access the web server with
Apache and Tomcat. Restart Tomcat did not help. Restart Apache helped. It could last for several
days no problem. After that, the problem happened again and needed to restart Apache again.
Once I downgraded Apache from v2.2.8 to v2.0.59 without other changes, the problem is gone.


I'm sorry to have wasted your time assuming that this was a problem that could be easily resolved.
It seems like maybe this is a difference in how mod_proxy handles stuff - I assume you're
using ProxyPass and mod_proxy_http.

I would suggest that you post your situation on , with
as much detail as possible, including your ProxyPass configuration.
