problem in jboss while configuring load balance with Apache

Dinesh venkatesan Newbie

Hi all,

 

I have done load balancing with mod_jk connector and Apache in jboss 4.its working fine.I can access the appklication in both webserver and application server also.

 

I am using jboss 4.3,mod_jk connector 1.2.28,apache 2.2.11.Everything is working fine but after sometime i am getting service temporarily unavailable error while accessing through web server.

 

I have seen mod_jk error log file its showing some error ..But the same application working fine in jboss. If i restart the jboss i am not getting any error and application working fine in web server also.

 

Error log for mod_jk:-
