This may indicate the app is not completely started.
Do you do anything in servlet init() method?
Is the app ok if you wait for some time?
What exceptions do you get in the server.log?
Thanks.

The server is restarted each night for sanity reasons (i also experienced some slow downs in the past if i did not). The problem is, that sometimes for some reason not all applications start up properly, they just answer with a "503 - The requested service () is not currently available." message. I could not find anything usefull in the server logs. It is completely random if and which instance does not start up, sometimes even more than one. I noticed that a manual asadmin start/stop-domain always seemed to fix everything whereas doing it in a cron job needs several retries but this could also have been just luck.

Ill attach its output from this morning at the bottom of this post. Interestingly, some applications/hosts crash more often than others but this, again, could be just coincidence.
