Does these workers options are valid with mod_jk2 (mod_jk2-2.0.43.dll) ?
No, mod_jk2 is deprecated since many years. mod_jk is well maintained
and the preferred way to go.
Do you think that the following message are relative to timeouts issues ?
"Error connecting to tomcat" (not necessarily the 4th) or ajp_process_callback write failed.
Not directly, they are what they say, namely errors when establishing a
new TCP connection to the Tomcat AJP connector. Timeouts help in making
the system generally more stable.

i got many errors about mod_jk but i don't know whether it's the good forum ...
I have configured 4 tomcat identical servers reached by a front server apache through mod_jk.
When I look at the jkstatus page, I can note a strange behaviour: only the same server (4) is under loaded.
Regular percentages are:
1st:30% , 2nd:29%, 3rd:28, 4th:13% (note: lbfactor is the same for the 4 workers)
What are therse percentages?
I don't know which way I can scrutinize.
I just can see a lot of errors within error.log:
"Error connecting to tomcat" (not necessarily the 4th) or ajp_process_callback write failed. Not good.
So, the question is, which are the first checkings at tomcat configuration I can do ?
Read about timeouts:http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html
All attributes are listed onhttp://tomcat.apache.org/connectors-doc/reference/workers.html
Do you have an "how to" for interpreting jkstatus ?
Not really. What about jkstatus do you want to interprete?
There's a bit of information onhttp://tomcat.apache.org/connectors-doc/reference/status.html
or is there any other way, a kind of pure tomcat tool, to check the tomcat perfs.
