Re: suse 9.1, tomcat5.0.27, mod_jk2, apache 2.0.13 problems
Thanks for the response! Actually these were fresh reloads. Are you running the same tomcat 5, apache2 versions that I am? -joe - Original Message - From: Quinton Delpeche [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: suse 9.1, tomcat5.0.27, mod_jk2, apache 2.0.13 problems Date: Tue, 30 Nov 2004 06:48:11 +0200 On Tuesday 30 November 2004 06:29, dawg fan wrote: Hello, Hi, We just reloaded many of our front-end servers to suse 9.1 from suse 8.2.

suse 9.1, tomcat5.0.27, mod_jk2, apache 2.0.13 problems
Hello, We just reloaded many of our front-end servers to suse 9.1 from suse 8.2. This release of suse of course has the new 2.6 kernel with a few other changes. That is the only change as we used the same tomcat 5.0.27, mod_jk2, and apache 2.0.13 configurations from the previous 8.2 server. These servers easily do over 100,000 http requests per server per hour. Under the new 9.1, we get many more mod_jk2 errors and the frequently occurring hanging apache child processes. This causes high cpu usage and causes the server to get slow and stop serving. To attempt a fix, apache was recompiled in 9.1. Problems still occur. Has anyone else noticed this performance issue?
