I got this error while accessing the rscd.log file via CM.
The same does not happen if I open another file (ex. the exports or the users files or others).
rscd.log* file are owned by root and they are correctly updated when I surf into the filesystem.
you need to use the 'bllogman' utility to access rscd logs from w/ in bladelogic. you can create a custom command for this, but you can't directly access the logs via nsh or via the gui.
