Summary: Possible memory leak in Stream Object

Initial Comment:
ooRexx 4.0.1 (Build 5/2/2010) on WinXP SP3

Should the memory usage for the following script continue to grow until hitting the 'PAUSE' or is this a memory leak?    

  Do myJ = 1 to 100000
     myStream = .Stream~New('c:\temp\test.txt')
     myStream~Open('Read')
     Say '>'myJ myStream~LineIn
     myStream~Close 
     Drop myStream
   End
 
  Address Cmd 'PAUSE'

Please note that I also posted this to 'Users' mailing list before noticing that this was the best method for support.

Thanks, Mike Draggs

There does seem to be some problem here.

If you watch the memory for rexx.exe in the Task manager as the program
runs, you can see the memory used steadily increases until the loop ends. 
Uses about 200 MB on my system with myJ going to 100,000.  If you set the
loop to go to 1,000,000 it uses about 1.2 GB on my system.
