Hi! We are using cocoon 2.1.5.1 in a linux production environment, JDK 1.4.2_05 and Tomcat 5.0.28. Sometimes (rarely!) after the tomcat startup, the first access to the cocoon webapp produces a cocoon initialization error complaining that the component org.apache.excalibur.store.Store cannot be found, but after a tomcat restart everything works fine again.
As this problem does not occur regularly, the cocoon configuration (eg. cocoon.xconf) should be OK. Any help would be highly appreciated! If the problem occurs, any request returns the following error: <html><head><title>Initialization Problem</title></head> <body><h1>Initialization Problem</h1><p><span>Message:</span> Unable to lookup
