You don't delete a an active log file just because if it is too big: it
won't help. Remember that in unix file systems there is actually no
operation called "delete". 'rm' uses the system call unlink to dettach
that file from the filesystem. However if the file is also linked from
somewhere else it will not be deleted yet. In this case it was still
open as a log file for Asterisk.

So what can you do?

1. find the process that holds the log file open and either convince it
to close the file or kill it. 'logger reload' was already mentioned.

2. don't delete (unlink) it: zero its content. Rather safe with a log
file, may not be so with some data files. e.g: 

  echo -n >olg/file
