Hi,
I've been getting a lot MsgAjp Overflow messages recently. The strange
this is only seems to happen only 1 app server at a time and seems to
stop and start in bursts of sometimes over an hour, but then nothing for
several hours after that.
This is with Tomcat 5.5.20 and mod_jk 1.2.23.
Is it possible that it is someone trying to provoke a DOS or should I
really investigate increasing the maxhttpheadersize in server.xml and
max_http_size in Mod_jk?
Thanks for any help,
Rob
