Unrecoverable Error 400 Request Failed
I've seen the apache mod_jk config page which seems to have a bunch of different parameters for dealing with "stuck" tomcats, but I'm unsure of which one to use, because I You can also look at what are the URLs, the user agents, the client IPs etc., all via the access log. - add an access log to Tomcat and do not In my httpwatch i see the request going without any> body ony header.Without the change in KeepAliveTimeout, can you reproduce this errorin your test environment?

Content-Type: text/plain; charset=ISO-8859-1; format=flowed Gang, I have a somewhat heavily loaded tomcat application that uses a fairly standard Apache 1.3.33 / mod_jk 1.2.15 / tomcat 5.0.28 set up. I think my current configuration is the worst version so far.

The request comes from the browser and hits the webserver and then forwards to the appserver instantly. Another thing I notice in the modjk.log, is that for this request, I only see the request header getting printed, don't see any body getting printed in the logs.

WhenTomcat send the next part of the response to the web server (e.G.Apache httpd), and the web server tries to send it back to the client(=browser), it detects a closed connection YesYou shouldn't be using any OpenSSL for the the AJP connector, soproxied requests via AJP shouldn't trigger the OpenSSL errors.

They are not caused by calling a special url but are caused by many different calls. Running this combination we were getting a lot of http status 400 error messages in our webservers access logs. It is a convenient method for setting directives that # are usually set inside workers.propetiesfile. have a peek at these guys These are load balanced by an Apache server running on the same machine.

It is also worthwhile to note that as soon as traffic picked up in the morning, the jk load balancer put both of our servers into "error" state and shut down
Better yet probably, restart from the default values for everything, and start modifying from the defaults only if you really have a problem.
Ok - i turn the logging level to debug - the course of events get more clear - but also more questions appear - there are socket numbers - which sockets You can disable it if you think doing so will improve thesituation, but I don't have any reason to suspect it would.It would be great to know whether the AJP connector The numbers are platform dependent.
