Hi Rainer, thanks for your response.
I tried the config you suggested. It suppose the way of configuring those
parameters is as you said, but skipping "manager." from the begining, as
when I tried as you said, I got this in the catalina. log:
10-mar-2009 15:58:19 org.apache.tomcat.util.digester.SetPropertiesRule begin
ADVERTENCIA: [SetPropertiesRule]{Server/Service/Engine/Cluster/Manager}
Setting property 'manager.sendAllSessions' to 'false' did not find a
matching property.
10-mar-2009 15:58:19 org.apache.tomcat.util.digester.SetPropertiesRule begin
ADVERTENCIA: [SetPropertiesRule]{Server/Service/Engine/Cluster/Manager}
Setting property 'manager.sendAllSessionsSize' to '200' did not find a
matching property.
10-mar-2009 15:58:19 org.apache.tomcat.util.digester.SetPropertiesRule begin
ADVERTENCIA: [SetPropertiesRule]{Server/Service/Engine/Cluster/Manager}
Setting property 'manager.sendAllSessionsWaitTime' to '0' did not find a
matching property.
10-mar-2009 15:58:19 org.apache.tomcat.util.digester.SetPropertiesRule begin
Maybe without the "manager" prefix? sendAllSessions=false,
sendAllSessionSize="200" and sendAllSessionsWaitTime=""?
Filip, we consider taking thead dumps, but we are using jdk 1.5 under
windows. I heard it is not supported in Windows until jdk 1.6. Is it true?
Best regards
Mikel
