Hi.
I have some servers with Apache2 + Tomcat5, with some virtual hosts
inside.
The servers are in production and nothing is reloaded. I've installed
the Tomcat Manager to reload those virtual hosts that suffers changes
from preproduction.
The problem is that many times the reload fails with that error:
Session already invalidated
and the context goes down, only that context.
Seems that this error appears when the context suffers any previous
Exception. After a Tomcat restart the manager reload works very well.
Here is the output error from the context log:
2004-12-30 18:47:03 StandardContext[/managerTomcat]Manager: init:
