Subject Re: mod_jk 1.2.10 and tomcat 5.5.9 buffer overflow
Date Thu, 14 Jul 2005 20:06:26 GMT
I've enabled the logging per your suggestions, and not having heard back 
in a bit, I was hoping someone could clue in to why I get plenty of FINE 
messages for org.apache.jk.common.MsgAjp,  but no  longer get SEVERE 
messages.  I'm also trying consistently crash mod_jk, but not having 
much luck, OpenCMS is the webapp invovled here, I haven't gotten any 
feed back from their dev list.
