Somehow my rails log files get deleted after some time.

The log files do get created properly when I restart my mongrel  
server. I usually have tail -f on the log files and they function  
well even after the files don’t exist anymore according to the file  
system.

I use the standard development.log and another other log file that I  
create as follows:

logfile\_query = File.open ( “#{RAILS\_ROOT}/log/query.log”, ‘a’ )  
logfile\_query.sync = true  
logger\_query = StatsLogger.new ( logfile\_query )  
silence\_warnings { Object.const\_set “LOGGER\_QUERY”, logger\_query }
