Perhaps you need an empty web page to go to and them go back to the desired page.

If there is a better way to refresh the web page than recalc variables, I am open to trying it. At 05:38 PM 2/17/2010, you wrote: Dan, Sounds like you are onto something. Can you avoid using recalc variables? There are other ways to get data to display without resorting to that. You can do your calculations in code and use property commands to update the form controls. But, before you do that, look carefully at your form expressions. Are the data types what your expect? How many variable controls do you have on the form? You might try making a copy of your form and start hacking variables and control out until you find the culprit.

I turned off all processing and just let the form run and refresh the web page over and over and over... No increase in memory at all... so the memory loss has to be in my coding. Then I did that again with a 'recalc variables' in the eep.... Boom Memory issue Eep calls the form... timer eep has... set v vcount = (.vcount + 1) pause 3 using .vcount RECALC VARIABLES return every round adds 500k So No Rbase processing going on... no while loops etc... Timer, web page, refresh. Open the form manually, it goes up Close the form just back to the R:Prompt Memory not released Re-open the form Memory goes up. close it back to prompt... stays up. Next Idea? Yes, Temp tables are created files imported, lots of processing done, files renamed files ftp'd to an off site source While loops are all part of the code that was running every 15 minutes. If I call the form manually, the memory is not released until the R:base session is closed. This code has been running unchanged 4 about 3 years or so. Not sure why just in the last three months it has become an issue. I am now running a sample of my code without the form, and putting it through a timed loop to see if it in fact is the culprit. If so, it might be just as easy as run them separate. I could easily close and open a second R:base on a timer and leave the web form open all day with no memory issue. Will do some thorough testing. Thanks everyone for your help. I will post my results. Dan 1. If you call the form manually, does memory increase when it is running and release when you exit the form? 2. Are you using a while loop, or my goto code in your eep?

Originally I would just refresh the web content... Memory usage increased Then I tried a closewindow, start new form... Had that in a wrong spot, and opened more and more forms. (my bad) Memory usage increased Now the start eep that calls the form originally is set up like you are suggesting... completely closing the form on each iteration of the loop. Memory usage increases. I am guessing the ONLY way to get the memory to reset is to close R:Base. If that isn't the case, that would be best for me as I don't know how to open an instance of R:base to a particular monitor. Without fixing this, This application uses up memory so fast that twice a day things fail. Have to manually start and stop it. Not good for an automated process. At 01:28 PM 2/17/2010, you wrote: Dan, I think your problem is nextelshuttle never completely goes away because it is calling another copy of itself. You should never have code that calls another form after closing the form. The fact that the memory is released when you completely exit your routine is a hint. Instead, set up a loop which calls nextelshuttle. The nextelshuttle timer should just closewindow after 15 minutes. No other code should be rum after closewindow. This way, nextelshuttle will completely close and release memory before being called again. You will need some way of setting vQuit to YESat the end of the day or when a button is pressed on nextelshuttle Label Loop set up some vars... set var vQuit = NO edit using nextelshuttle if vQuit = YESthen goto Endloop else goto Loop endif Label EndLoop Dennis McGrath ________________________________ From: [email protected] [ mailto:[email protected]] On Behalf Of Dan Sent: Wednesday, February 17, 2010 11:59 AM To: RBASE-L Mailing List Subject: [RBASE-L] - Re: Memory Usage out of hand Ok, I made your suggestion work, and closewindow is working now, but I think I need to actually close R:Base to free up the memory? (Memory usage goes up by 50,000 k every loop) So, if that is the case, how do I have R:base open to a particular screen (I run a 4 screen setup here and the app I am working on has to be on the upper right, or Monitor 3) At 11:30 AM 2/17/2010, you wrote: Ok, Yes, Rbase Dat calls up the form: set up some vars... edit using nextelshuttle exit Nextelshuttle form timer does the 15 minutes, and calls an internal eep That eep, does : Closewindow run nextelshuttle.dan return The nextelshuttle.dan does lots of database stuff, and then edit using nextelshuttle The closewindow does not close the window, but a second form is generated (and third and so on for each loop) If you close the latest loop, all forms close. No memory is released till all forms close. What am I missing? Dan At 11:00 AM 2/17/2010, you wrote: Somewhere you have a program that calls up your form, maybe RBase.dat or something else. Do the following (or something like it depending on how your system works): your program: LABEL formagain SET VAR vExit TEXT = NULL EDIT USING nextelshuttle IF vExit = 'yes' THEN EXIT RETURN ELSE GOTO formagain ENDIF RETURN In your Nextelshuttle form: You would have a button to exit the form totally; that form's eep code would be: SET VAR vExit = 'yes' CLOSEWINDOW RETURN And somewhere there's code that does the 15 minute timer. In that code when you've reached the 15 minutes, the eep code would just have: CLOSEWINDOW RETURN or you can use the pre-defined "exit" action. Important: you need the "return" even if you just have closewindow on there. Karen So, now that we have surmised that my memory issue is the use of IE, I am trying to find a way to have the program close and reopen the form each loop through. Closewindow doesn't seem to be my answer. Anyone have any good ideas? Problem: I run an instance of R:base that opens just one form 'edit using nextelshuttle' The form has two objects, a clock and a web object that displays a city map with all our technicians on it. that form has a 6 minute timer to run an eep that refreshes data, imports info to the database, after the eep, the web refreshes. (this is where the memory loss is) I was hoping a closewindow would work, but I cannot make it close the form and restart a new form. I suspect though that I would need to close that whole instance of R:base to free up the memory. Thoughts?
