Mod_JK 1.2.23 error 200
folks,
I currently try to load my application using OpenSTA by simulating 1000
virtual users. having a quick look within mod_jk.log, it seems that I
have a problem with my load balancer... connections dropped ??
My configuration: apache 2.0.59 /mod_jk 1.2.23/tomcat 5.0.28
_____LOG____
[Tue Jul 10 11:42:43 2007][9648:19296] [info]
ajp_process_callback::jk_ajp_common.c (1448): Writing to client aborted
or client network problems
[Tue Jul 10 11:42:43 2007][9648:19296] [info]
ajp_service::jk_ajp_common.c (1857): (helios1) request failed, because
of client write error without recovery in send loop attempt=0
[Tue Jul 10 11:42:43 2007][9648:19296] [info] service::jk_lb_worker.c
(1068): unrecoverable error 200, request failed. Client failed in the
middle of request, we can't recover to another instance.
does this error already occurs to someone ?? is there any solution ?
thanks in advance for your help...
Phi-Long

i probably find out the reason why connections failed... trying to load,
my app with up to 1000 users I get this error:
----log----
vhpuw51:appmig grep MaxClients *
error_log:[Wed Jul 11 12:02:52 2007] [error] server reached MaxClients
setting, consider raising the MaxClients setting
----end log----
So i guess I have to increase the MaxClients value (currently 256) but I
read something like I have to recompile apache after amending httpd.h...
however I did not find the HARD_SERVER_LIMIT entry within it.... is it
still an accurate info for apache 2.2.4 ?

It looks like OpenSTA uses a timeout and your responses are to slow. Add
"%D" to your apache access log format to learn about response times.
Most likely OpenSTA will tell you about timeouts too.
The messages are only infos, the system works in principle, but a lot of
client abort messages might mean, that the system is to slow.

Rainer
