Re: Re: Is it a Memory leak???
Tim, Is it that JVM bundled in Windows and Linux are different?? I have tested in Linux 7.2 and there is not memory increment. It hovers around the same value. This happens in Win2k. The parent process eats up enough memory. Satya. On Sun, 05 Oct 2003 Tim Funk wrote : The JVM does not release memory back to the OS.

Chuck, In fact I've upgraded from Tomcat 4.0.4 to 4.1.27. I have precompiled JSPs w.r.t tomcat 4.0.4. Do you want me to compile them w.r.t 4.1.27 and retest?? Satya.

Re: Re: Is it a Memory leak issue???
Fillip, I have a separate script for compiling the JSP files, which is used for compiling the JSPs. Can you please tell the significance of the fork flag?? I wonder, if it has someting to do with the OS. As in Win2k we have a fork process concept for Apache. Satya.

Is it a Memory Leak in Apache 2.0.47???
Hi, 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 ProcessNo.Of Pages Running Time (in KB) (in KB) (In min) 38127952 Nil 10 381212,9922520 381215,128140 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.

Compilation Error !! mod_jk.dll, Apache 2.0.47 + Connector 4.1.27
Hi All, I am getting a compilation error while generating the mod_jk.dll for Apache 2.0.47 and Connector 4.1.27. These are the steps I followed. 1. Took the sources of Apache and Connector and set APACHE2_HOME and JAVA_HOME. 2. From the prompt I run, MSDEV mod_jk.dsp /MAKE ALL. (VC++ 6.0) 3. Intially it threw error w.r.t Apache jk_uri_worker_map.c. Then I took the latest one from CVS , 1.84 version. The error got resolved. 4. Now I am getting an error as Compiling... mod_jk.c C:\Satya\downloads\Apache_Src\httpd-2.0.47\include\ap_config.h (58) : fatal error C1083:Cannot open include file: 'apr.h': No such file or directory Error executing cl.exe. I tried to take the latest one of ap_config.h from CVS . But the same problem persists. I could not find the apr.h. All I can find is apr.h.in, aph.hnw and apr.hw. I am trying to get het .dll file for a long time. But unable to find any workaround. Your help is gratefully appreicated. Let me know if it is an issue or I have to include something else.
