Update :

After further testing, the problem actually does not come from the different 
Tomcat version but from the upgrade to version 4.2, and happens on both 4.1 and 
5.5 versions of Tomcat.

Also, after a few thousands hits, Jahia starts to be really slow (response time 
> 10 seconds) and to use up very high amounts of CPU (~300% -> 3 out of 4 cores 
at 100%). This does not happen before the 4.2 patch, for the same data (same 
databse, same content files).

Anybody any idea what it comes from ?

Thanks in advance,

Pierre Henry

Hi,

I am currently migrating from Java 4.1 to 4.2 and Tomcat 4.1 to 5.5.

When under Tomcat 5.5 (with the same template set), I get the following type of 
warnings each time I hit a page. The page is then displayed correctly, but it 
seems to slow down the rendering considerably. When immediately reloading the 
page, the messages don't appear (caching) but if re-hitting the page after a 
while (even without restarting the server) they come again.

189361 WARN  [org.jahia.data.containers.JahiaContainerSet] - Definition for 
field <jahia-resource id="unine_formation_unine_portal_templates" 
key="titleMandatory" default-value="Titre <span 
style='color:#ff0000;'>(obligatoire)</span>"/> (in boxContainermain_1) has 
changed.

189374 WARN  [org.jahia.data.containers.JahiaContainerSet] -  Title has changed

default-value="Title <span style='color:#ff0000;'>(mandatory)</span>"/>
189374 DEBUG [org.jahia.data.containers.JahiaContainerSet] - Setting data for 
pageDef 40

As far as I have seen the messages are of 3 types : "Title has changed", 
"Definition has changed" and "Default-value has changed".

I haven't edited anything in the JSP's that contain the definitions !

I have activated "DEBUG" logging level on the org.jahia.data.containers package 
but it didn't bring much more details (only the "setting data for pageDef XX" 
messages).

What do these messages exactly mean ? Are they maybe normal ?

How could the change from one version of Tomcat to the next trigger this ?

Please excuse me if some of the answers are obvious but I didn't write the 
templates we are using and don't have much experience with writing Jahia 
templates in general.

Thanks in advance,

Pierre Henry
