Hi,
I upgraded apache from 2.2.22 to 2.4.4 with mod_jk connected to tomcat server. Apache often goes to unresponsive state. After deep analysis I found some problem in Apache with IPv6 & IPv4. To resolve this I made changes like 0.0.0.0:80 in httpd.conf (& ssl.conf).
Then the server was seemed to work fine, later it again became unresponsive.
Here are some log traces:

.
Upon analyzing with TCPView tool, all apache thread are not freed.
System Configuration:
Windows 7 64bit (Dual Core)
Apache 2.4.4 & mod_jk 1.2.37
ThreadsPerChild 200
No. of requesting client is less than 10.
Any help on resolving this is highly appreciated.
Thanks
