While I've not seen this issue before, I'd first double check that Tomcat can write to the log directories.

Check which user Tomcat is running as (probably: ps ax | grep java) and then the owner of the logs directory (ls -ld /path/to/idp/logs).

Might be worth checking the tomcat logs to see if they show anything, too.
