> The problem is that each time ActiveIO checks to see if control.dat is locked
> it creates a new java.io.RandomAccessFile. If the control.dat file is
> locked, it fails to close the RandomAccessFile.
> This exception always will be thrown from an instance in Shared-File-System
> Slave mode that continues to check the Journal file (which the Master has
> locked). But the rate at which is is thrown depends on the maximum number of
> files the OS allows to be open. You can check how many files are open with
> 'ulimit -a'
