Mod JK Connector Error Codes ?
I have Apache(2.0.55) and Tomcat (5.5.12) connected via the Mod JK (1.2.15) connector, setup and running on a Linux RedHat Enterprise Edition. On startup of Apache I get the following error in my Mod_JK.log file: [Fri Mar 17 13:51:46 2006] [error] init_jk::mod_jk.c (2370): Initializing shm:var/www/tomcat/ROOT errno=2 [Fri Mar 17 13:51:47 2006] [error] jk_child_init::mod_jk.c (2326): Attachning shm:var/www/tomcat/ROOT errno=2 [Fri Mar 17 13:51:47 2006] [error] jk_child_init::mod_jk.c (2326): Attachning shm:var/www/tomcat/ROOT errno=2 I have been trying to find what this errno=2 is actually refering too but can not find any documentation containing the list of error codes for the Mod JK connector. Although I get this error the website seems to function correctly. Can somebody please tell me what error code 2 actually is ? Or better still refer me to a list of all the Mod JK error codes ?

RE: Mod JK Connector Error Codes ?
Correct me if I am wrong but I believe I am using the JK module and not the JK2 module I am using version 1.2.15, and believe this is the version recommended by Apache for a production environment ? There is definitely no SHM file located in my logs directory. What does SHM stand for ? And what is it ? -Original Message- From: Vanessa Campos [mailto:[EMAIL PROTECTED] Sent: 17 March 2006 16:11 To: Tomcat Users List Subject: RE: Mod JK Connector Error Codes ?

In my case, while TomCat/Apache are active, there is a shm.file on apache log directory.

RE: Mod JK Connector Error Codes ?
Neil, That's what I was trying to tell you. There is no way to set shm file on mod_jk. It's default location is on apache log directory. Did you check you conf files to see if there is any where a missing / on var/www/tomcat/ROOT? I thought the correct string was /var/www/tomcat/ROOT... Then, if this is correct, mod_jk is really trying to write to an invalid drectory. --- Neil Sherman [EMAIL PROTECTED] escreveu: Correct me if I am wrong but I believe I am using the JK module and not the JK2 module I am using version 1.2.15, and believe this is the version recommended by Apache for a production environment ?

RE: Mod JK Connector Error Codes ?
My httpd.conf file has a bunch of include statements at the bottom of the file (so that I can keep each virtual hosts configuration separate) e.g. ... Include conf/siteA.conf Include conf/siteB.conf Include conf/siteC.conf ... Each of these include files looks like: VirtualHost 1.1.1.1:80 # Set the document root folder DocumentRoot /var/www/tomcat/webapps/siteA/ROOT # Set the name of the server ServerName siteA.com # Set up the alias for the maps Alias /maps /mnt/siteA.maps # Mount the worker JkMount /*.jsp LBsiteA # Set the server admin ServerAdmin [EMAIL PROTECTED] # Set the log files ErrorLog |/usr/local/sbin/cronolog /var/log/apache/siteA/%Y/%m/error_%Y_%m_%d.log CustomLog |/usr/local/sbin/cronolog /var/log/apache/siteA/%Y/%m/access_%Y_%m_%d.log common # Set the directory security Directory var/www/tomcat/webapps/siteA/ROOT AllowOverride All Order allow,deny Allow from all /Directory /VirtualHost The actual error message returned in the mod_jk.log file is [Fri Mar 17 13:51:46 2006] [error] jk_child_init::mod_jk.c (2326): Attachning shm:var/www/tomcat/siteB/ROOT errno=2 Strangely if I uncomment the include for Site B in my httpd.conf file I then receive the following error: [Fri Mar 17 16:30:46 2006] [error] jk_child_init::mod_jk.c (2326): Attachning shm: errno=2 If I uncomment all of the includes I see no errors in the mod_jk log file. Strangely if I uncomment all of the includes except for just one, I also see no errors in the log file, and it dosen't matter which one is left in. This leads me to believe that the actual paths etc are setup correctly otherwise I would receive this error whenever a specific include was not commented out. It looks like I am hitting some limit ? Perhaps the number of allowed connectors ?
