I'm having the same issue as documented in:
http://www.nabble.com/httpd-JK-Tomcat-hung-connections-td10403182.html
For our situation, we haven't hit the "server reached MaxClients setting"
issue yet, but we easily could.
We also have this same config running on a Windows cluster and that
environment seems to clean up after itself without any issue.
Does anyone see any obvious misconfigurations below?
Also, in a probably not related issue, when I look at the jkmanager page, I
see lots of garbage characters in the RR and CD columns, but only in certain
rows.
It looks something like:
!%���E�� * ��{ZQ�` l��=� �j��8�U���4_~GT��V
When I installed mod_jk, I tried the binary as well as compiling the source
myself. Both options still showed the garbage characters.
Thanks,
Darin Pope
