I was looking at some of the log files the other day for FM7SA. All seems ok except the "web_server_module_log.txt."

Throughout this file there are several (thousands) of entries such as:

[Thu Feb 24 13:45:56 2005] [jk_ajp_common.c (681)] ERROR: can't receive the response message from tomcat, network problems or tomcat is down.

[Thu Feb 24 13:45:56 2005] [jk_ajp_common.c (1050)] Error reading reply from tomcat. Tomcat is down or network problems.

[Thu Feb 24 13:45:56 2005] [jk_ajp_common.c (1187)]: ERROR: Receiving from tomcat failed, recoverable operation. err=0

or:

[Tue Mar 15 10:59:36 2005] [jk_ajp_common.c (1198)]: Error connecting to tomcat. Tomcat is probably not started or is listenning on the wrong port. Failed errno = 61

[Tue Mar 15 10:59:36 2005] [jk_isapi_plugin.c (928)]: HttpExtensionProc error, service() failed

Does anyone know what may be causing these errors, and if it's something I should be worried about?

Tomcat enables the web server to use Java and JSP servlets (faceless apps on the server providing functionality). It is installed and used by FMSA.

Clearly tomcat is not running on your server. Did it ever work? if not, try reinstalling FMSA. If it did, check the web server's error logs for more clues (perhaps a config file got corrupted).

If you reinstall FMSA, I advise removing it completely first so nothing remains (FileMaker .fp7 files are OK), then do a clean install. It's easy to get tomcat screwed up if the EXACT steps are not followed during installation. One case where you absolutely need to RTFM.

These errors happen all the time, and if everything's responding properly otherwise can be ignored. We've spoken with FileMaker in the past regarding such, and they've verified this behavior.

Wow. My web_server_module_log.txt has the same errors, it looks like everytime I accessed a database using IWP the set of errors occurs.

John - Thanks for clarifying this.
