Hi to all...
I'm using apache2.2 + tomcat6.0.18 + mod_jk1.2.28 for our portal.While doing
load test with 20 & more users, I try to access the application through
browser but pages are getting loaded and in mod_jk.log file I'm getting the
following message,
[Fri Feb 26 12:50:25 2010][304:728] [info] jk_ajp_common.c (1788): Writing
to client aborted or client network problems

error (attempt=1)
