Rainer,

i've forgotten in my last message;

Does these workers options are valid with mod_jk2 (mod_jk2-2.0.43.dll) ? 
(http://tomcat.apache.org/connectors-doc/reference/workers.html)

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.
