Hi, Bradley,

Can you be more specific on what do you mean by /rvm fill up ?

RVM use two files (or partition): log file and data segment.  Both of
them have fixed size.  When space in log file are used up, RVM will
"truncate" the log, which means RVM will reflect the transaction
records in log file to data segment and hence reclaim the space.  Log
truncation is done automatically when the log is filled up above a
preset threshold, currently it is set to 50 percent.  The log will
also wrap around, so it has fixed size and should not fill up the
partition where it lives.
