[opencms-dev] critical error during opencms initialization

[Christoph P. Kukulies]

We stop and start Tomcat6.0.10  and Apache2.2 every midnight during the
backup of our intranet machine.

Since a couple of days the first access in the morning, when the
secretary wants to log into opencms, produces the error below:


HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented
it from fulfilling this request.

exception

org.opencms.main.CmsInitException: Critical error during OpenCms
initialization: Unable to initialize the user driver. 
	org.opencms.main.OpenCmsCore.getInstance(OpenCmsCore.java:290)
	org.opencms.main.OpenCmsServlet.doGet(OpenCmsServlet.java:127)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:690)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

note The full stack trace of the root cause is available in the Apache
Tomcat/6.0.10 logs.
Apache Tomcat/6.0.10


Looking into Tomcat/logs/stdout_20100226.log I see:



--------------------
The following critical error occurred:
Critical error during OpenCms initialization: Unable to initialize the
user driv
er.
Giving up, unable to start OpenCms.
--------------------
log4j:ERROR LogMananger.repositorySelector was null likely due to error

Anyone seen this or have an idea? Looks like some weirdness with log4j.
