Hello and thank you,

The error message reads as follows:
'org.apache.catalina.LifecycleException: Failed to start component
[StandardEngine[Catalina].StandardHost[localhost].StandardContext[/APPWARFILE]]'

And the rest of that message? What does the stack trace show?

There may also be earlier errors in the logs that are relevant.

There are two app files trying to start, and both are getting the same
error. The weird part is, these app packages were not touched since before
the summer. Server patches have happened since, but this is the first month
where Tomcat is doing this So, two key notes:
1: app packages have not been changed.
2: hot and warm servers have been patched, but only hot servers received
this Tomcat error. This is the first month I've seen Tomcat not start
properly, which makes me believe it's Tomcat.
Also, just FYI, this is for Tomcat 8.

Very respectfully,
Darious

Betreff: Apache Tomcat started, but error 404

Hello, trying to see if anyone else had this issue. After a reboot of
hot and
warm servers, my sites using Tomcat throws the error 404 only on the hot
servers. I've stopped and started Tomcat services, nothing. In the logs,
there
were 2 errors. One was Catalina. But even though the error happened on
hot
and warm servers, warm sites are still working, so I'm thinking that's
not it. The
other error on the hot servers says startup error. Is it just luck of
the draw, of
starting/stopping Tomcat services?
Is it something else, entirely? Frustrating that Tomcat does not have a
UI to
make this easier. Thanks in advance.

Very respectfully,
Darious

Could you past the error message about startup issue?
404 sounds like your application failed to start but Tomcat is running.
So it might be an issue with the application.
In the log files there are usually information about the reason.

Greetings, Thomas
