I'm desperate and throwing myself on the mercy of this mail list. I have an irate customer who wants this problem solved quickly. I have used MetaCard to create software which we use to monitor and control our distributed lighting control systems. It does these things very well. I currently have a job which requires that I poll the status of all my controls every 30 seconds. I do this so I can catch any changes of state and a close approximation of the time at which that change occurred. I also use this function to catch any errors in operation. The problem is that the time it takes to poll all the controls becomes increasingly longer the longer I run the software. Initially it will take 33 seconds to poll all of my controls if the polling interval is set to 30 seconds. After three hours it will take 43 seconds. By the next day it will take 2 minutes. If I poll at a faster rate, the application will become slower at a faster rate. I'm using it on Win2k SP3 but the problem also occurs on Win98. This problem occurs even when I turn off all other functionality so that the only thing it does is get the status of all the controls at each interval (no logging of changes or errors, no triggering of timed events). The problem does not occur if I run the software without being connected to a system. The problem does not occur if I'm just connected to one of my controls which is not changing state. It appears that the retrieved information needs to be changing at least occasionally. I'll see some increase in memory usage as this problem worsens but I'll still have a huge amount of free memory. The processor usage goes up significantly as the problem worsens. It will start at just a few percent (I'm monitoring this with the Performance tab of the windows tack manager) Then continually increase as the problem worsens. The only way I've found to clear the problem is to shut the software down then restart it. I do not have to restart the computer. I tried using Memturbo to recover memory while my application was running but, no luck. Is there any way to get MetaCard to dump all the resources its using without shutting down? Does anyone have any other ideas? I spent all last week on the jobsite getting nowhere and could really use some suggestions. Thanks.
