Hello happy people.
I'm experiencing certain troubles with httpd (provided by WebStack 1.5) on Solaris 10
After a network hickup (I suspect) httpd refuses to answer.
The Process lingers in a state of waiting for the network interface, see the truss below.
It doesn't recover from this state until after restart.
This httpd is configured to serve as (SSL-Offloading) AJP Proxy. It's also used
for executing PHP applications using mod_php5.
