strange things

[rainer juenger <ja...@projektinter.net>]

Hi,

Everything just used to work fine for weeks! All of a sudden we are getting an error 503 back:
Servlet action is currently unavailable.

- we checked the rights of the files on our SuSE Linux Server, running Tomcat 4.01 under JDK 1.3.1_02
- restarted the server several times
- compiled the ActionServlet 100x 
- tried to access it dirctly not via *.do transformation configured in web.xml
- Did not cange the struts-config.xml since quite some time

Could you give us a hint?

thanks, Rainer

The log is as follows:
