Hi,
I have the default server.conf file with :
<Connector port="8080" protocol="HTTP/1.1"
maxThreads="250"
connectionTimeout="20000"
redirectPort="8443" />
I do not have any Executor.
When I check the manager status in detail I see the threads with ? in front
and nothing else. The ones being used do have the data.
Just wondering is it normal to have that much open threads waiting?
And André I have 4 Gb for each of the servers.
