Anyway, I was able to migrate to Apache to 2.0.47 and Tomcat 4.1.27, after lot of intial hiccups. The connector is mod_jk and they are running smothly in Windows2k and Linux 8.0.
I've an interesting observation. Feeding line feed characters to Apache 2.0.40 (which) was my earlier version, lead me to memory exhaustion. (Fixed in SECURITY [CAN-2003-0132]: Apache 2.0.45),but did not happen in 2.0.47. Nice...
But...but, when I load Apache / Tomcat with enough JSP / Servlet/ HTML requests the memory consumption is increasing and Apache does not seem to release it.
My Application Configuration:
1. Apache serves the HTML pages and JSP/Servlets are redirected to Tomcat. (Connector - mod_jk / AJP13)
2. Tomcat has no role to play to serve the HTML pages.
(non-SSL Coyote HTTP/1.1 coyote port is commented out)
3. Apache and Tomcat are running as two independent threads, with
Apache starting first.
The memory consumption, for win2k, is shown in this table.
(This is w.r.t. Apache 2.0.40 and the same thing is repeated in Apache 2.0.47. )
Parent Process Child Process No.Of Pages Running Time
(in KB) (in KB) (In min)
3812 7952 Nil 10
3812 12,992 25 20
3812 15,128 140 20
140 21,444 302 20
The memory consumption goes up and if I am killing my clients
(which sends HTML/JSP/Servlets requests), then , it hovers aroubnd the same shoot-up value.
Now, can I conclude, if I am bombarding Apache with enough JSP / Servlet / HTML requests, the memory leak happens???
Let me know about it.
Thanks, Satya.
