asterisk users - Dec 2005 - What would prevent logs from being recreated if they are deleted?

Hi,

Please excuse the cross post but these seems to be one of those issues 
that may be answered by a developer or someone with direct 
administrative knowledge of the deep workings of Asterisk. I have 
deleted my log files expecting them to be recreated by Asterisk 1.2 but 
nothing happens after a reboot or any of the log commands in the CLI 
interface ('logger restart', 'logger rotate', 'logger show
channels').
What would prevent these files from being recreated and what mechanism 
recreates these logs after being deleted?

Thanks
