mod_jk timeout/retrys when one load balaced server is down

[Kretzer Markus <mk...@buhl-data.com>]

Hello,
 
we are using mod_jk as a load balancer in front of 2 tomcats which are not running on the same server as the apache/mod_jk (the tomcats are actualy in another net zone after a firewall but that should not be important).
 
When one of the tomcats fails the failover to the other server works fine after 3-5 Seconds. But if the whole host goes down (Network cable plugged out, Host switched off) the failover takes ~60 Seconds, because the mod_jk tries to connect about 6-10 times with the tomcat and runs into a timeout every time. After that the failover works. But after a few minutes the whole process starts again and some of the users have to wait 60 Seconds before the website appears. 
 
So how do i set the timeout to a lower value? Or can i at leased set the retry to 1 or so?
