Logging just stops after service start up. Maybe it's dying of old age. Since you aren't using a package-managed version of Tomcat (and aren't at the mercy of the package-manager), why not upgrade to a version of Tomcat that is riddled with fewer security problems than 6.0.18? Maybe like 6.0.53, released during the current decade. Better yet, upgrade to Tomcat 8.5. If you aren't able to do this now, you should really start looking at doing it in dev/test environments so you can upgrade in the near-future. > The setup is such a way that the control flows from a Apache > Webserver to Jboss application server to Tomcat server.

Or do you really have a separate Tomcat that JBoss is talking to (JBoss being a reverse-proxy, or something similar)? > Just to give you an insight we are using source code based tomcat > server and not rpm based.

You just swapped the IP addresses of two servers and the problem "moved" along with the IP to the other server? > Please let me know what else needs to checked in order to make > this working.

Are you getting no logs from the application, Tomcat, or both? Tomcat isn't very chatty in catalina.out once it starts up. Really, you should only be seeing critical errors, or notices about application (re)deploying, etc. Does your application log to System.out? If not, I wouldn't expect application logs to go to catalina.out. > Details of troubleshooting done so far : > > 1. Cleared the logs, restarted the service – No luck. > > 2.

If you are talking about application-logs, you're going to need to provide more information, such as how the application performs logging in general. Are you using an API/framework such as log4j or slf4j? Probably not, if you are using an ancient version of Tomcat like that. Java-logging using java.util.logging? Hmm... also probably not. Are you using ServletContext.log() to perform logging? If so, those logs should be going to an application-specific log in the logs/ directory. - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQJRBAEBCAA7FiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlqfAkMdHGNocmlzQGNo cmlzdG9waGVyc2NodWx0ei5uZXQACgkQHPApP6U8pFiknw/+K+Su0g4BKhbS/ESk xZtqVjDhdd3besh07OukFdquxUzPKottHTPk7Xex7DWwOreOYb3Qtho1UvCpeYOt s2JxsEFGSIIZZlJrlJtoEwfmhsbw1dIocMfSygXtKOH4JrlQOypcoT2sS2Fj5Dql ATIgjvGehZptSKV9R1kwStfVxSrXuiTu281UImwx0wigRM5sw1nZRQBHZ5mDy9VE sVZFNjjpzdP9HpL0g5ZsXM37bDQfsRYlauhvQf1oyDHRu8cMpBOLwm7tpgHat68z DmDHGMtoUalr+TI7zObvmncyuBE70JRj9/MDlo8v/8XqlLwj/12TGcE59KoO2SsC VU8Gp4+FvtaBTlvLukZNgjtkhuJAPhzIG+QpPX7OxNLV2/h56Ej3nAMB5S2WYFJx gESk7bbwSd38rvaIpu3uN9HKQZhq+HYYbZ3grygpjpsPk9t75ihp5EhpLkwtXNiw I76Exu6TTlEWUx1CUso7sfGmgxsslPBPaNKmilQb+hgjoieiH1ulqBQ+HW5fpeZ2 8XTPvysyr/sw6+k8nIsUbE4QEyO+4tpNjMaZjrLMEOr5oOoC/SWzIs9g/NwGANWP hKTa1WJQXk7IhafLDjTCzJcC6WVtGmb+nbtyLNCSOPbl6oVLScLYPHLfbEpU91zG 8rhxWavnYzmJYlqBybjnqgFszvU= =w3Oa -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
