Tomcat Memory Problems and WebTrends

["Turoff, Steve" <St...@tenethealth.com>]

Greetings,

I am running Tomcat 4.1.24 and Apache/1.3.19 (Unix)  (Red-Hat/Linux). Every night, a WebTrends server makes a request to every page in the Apache access_logs. I believe this is to obtain the HTML title for the WebTrends reports. I've noticed that when WebTrends makes it's requests, Tomcat's memory starts to climb dramatically. I modified httpd.conf to pipe the access_logs into a script I wrote which outputs the line from the access_log (actually a shorter custom Format) and the amount of memory that Tomcat is using. I've attached a sample at the end of this email. As you can see from 03:36:59 AM to 04:01:15, Tomcat's memory almost doubles. On some nights, Tomcat actually stops accepting requests and I have to kill all of the java processes in order to restart Tomcat. I've attempted to recreate this problem using The Grinder (load tester), but cannot do so.

Can anyone think of why requests from WebTrends would cause this problem?

Thanks,
Steve

You can configure webtrends to not pull the HTML title. That is all webtrends 
is doing. (I think). If you don't need the HTML title inyour report - woohoo 
- problem solved.

PS: I hate webtrends
