Hi Art,

Yes, there's a configuration section in ldmadmin.  The number of logs is set to 
4 by default.  But, you decide if it's really worthwhile to keep more logs - 
the vast majority of the time 4 seems to be plenty.   If this is truly only an 
aberration, then ... it won't happen again! :)   If it does happen again and 
you aren't able to stash the appropriate log then I would be more inclined to 
suggest increasing the number of logs.
