Memory increasing
in [Visual Objects]

From: Bernhard Mayer on 5 Aug 2010 03:14 Dear fellow VO'ers! In my application I have a timer function doing some import work; every time the timer is fired (~ 10 seconds) I can see that the application's used memory increases in the task manager whereas the VO functions Memory(MEMORY_REGISTERAXIT) DynInfoUsed() show constant values. What can I do to force VO to release the used memory? I tried CollectForced() and DynShrink() with no success. It is definitely a problem if the application runs for a few hours on terminal server systems. Writing a service doing this job is planned in the future but is not possible now. Using VO 2.831 TIA, Bernhard

From: Klaus on 5 Aug 2010 09:10 Hi Bernhard, i had the same some time ago, after a restart of the task manager the memory where low again. Thought the task manager blocks the memory. regards Klaus On 5 Aug., 14:24, "Bernhard Mayer" <Idonotexisth...(a)nowhere.com> wrote: > In addition: Memory(MEMORY_STACK_FREE) and Memory(MEMORY_STACK_SIZE) are > constant, too. > > "Bernhard Mayer" <Idonotexisth...(a)nowhere.com> schrieb im Newsbeitragnews:4c5a64ba$0$19172$91cee783(a)newsreader03.highway.telekom.at... > > > Dear fellow VO'ers! > > > In my application I have a timer function doing some import work; every > > time the timer is fired (~ 10 seconds) I can see that the application's > > used memory increases in the task manager whereas the VO functions > > > Memory(MEMORY_REGISTERAXIT) > > DynInfoUsed() > > > show constant values.

Bernhard. But why do you say you have a problem? Does the app crash? How much memory is assigned that you are worried over? Did you watch your app for 10 hrs? Basically, this is entirely normal windows behaviour. Usually the OS will not request dynamic memory back from an application unless it really needs it. It is often cheaper to let an application keep the memory space it used than reduce it, thus forcing the application to continually reallocate. The second thing to remember (from a TS perspective) is that your VO application is restricted to 16MB of dyn RAM unless you did something to increase that deliberately. So no matter what, your app has a natural ceiling. The rest is OS management and I wouldn't bother worrying.
