I normally run with Firefox open with 3 or tabs active and Atomic Time 22 running in the background. When using WSPR I can also have Spectrum Labs running as a foreground app for days on end with no problems. When running Lentus (sans WSPR and SpecLab) my system becomes unstable after a few hours which makes me suspect there may be a memory leak. The instability manifests as slow (or no) response to mouse clicks and an inability to update graphics in windows other than the one occupied by Lentus.



I am using WinVista Home Basic on an HP with 1.8GHz Sempron processor and 1Gb RAM.



Has anyone else noticed anything similar?

Prob more to do with Vista (Vista is garbage). Suggestyou look into XP, its working fine here with all those same programsopen.

Au contraire, mon ami. Vista is not the problem. I was a Win98SE diehard due to bugginess I experienced on XP machines. When I got the Vista computer I was going to reformat the hd and install 98SE but decided to give Vista a try. I'm glad I did since it is even more stable than 98SE which is more stable than XP.



If the problem is due to the operating system it would exhibit itself when running WSPR or JT65HF multitasking along with my usual plethora of other apps.



I have done enough programming over the years from Win95 through Vista (and Microware OS9 Level 2 prior to that) to have developed a sense for whether something might be amiss in the coding. In my own coding efforts such instabilities were almost always due to late rather than early declaration and binding of variables and/or buggy or missing garbage collection routines.

Ok, then perhaps hardware/Bios is the culprit myfriend. As I say, I have all those same programs here, and it runsnicely in that config on an AMD dual core with 2gb memory, on aGA-M61P-S3 Gigabyte Mobo.

I also have to keep a W98 box alive here, mainly because of LMR Radioprogramming software which needs real DOS to run on.

Is there a Bios upgrade for your Mobo? Ive found many undocumentedimprovements sneaked in during upgrades.

I doubt if it is hardware or Bios related since the same hardware is used.



Its an old programming truism that a multitude of sins can be ignored if you have memory and cpu cycles to spare. No disrespect to Patrick... after all, beta testing is meant to reveal any peculiarities or deficiencies in the coding. "Negative" reports are just as (or more) valuable to a developer as positive reports.



I am going to leave only Lentus running in rx-only mode while I'm at work today. I have already terminated all unnecessary system related routines using Task Manager and will shut down Firefox before I leave for work. I'll be shutting down Firefox also. Then I'll have a somewhat better idea of what's happening when I get home after about 10 hours of running time.

Hello Bear,



I have also Vista Home. My PC is working days and nights (for Lentus

testing) but I did not see such behavior.

However, I will check if the processus memory increases.

Patrick,



At the moment with only Lentus and Firefox running I am seeing stable memory utilization with the performance monitor in Task Manager. About 53% free memory out of 1Gb and cpu utilization varying between 10% and 30% but mostly below 20%.



The trouble may be due to some thrashing occurring while multitasking with other apps.



Thanks in advance for checking.



Now off to slave in the salt mines.

Hello Bear,



Finally, I discovered the reason of such size: the 90 Mb corresponds to the

sum of the file itself and all the memory reserved in the program (public,

private variables + stack).

I don't know exactly why the program size does not directly go to 90 Mb.

The big step was the JT65 (43 Mb necessary).



For Multipsk 4.21: 78 Mb memory needed + about 3 M of stack + 9,4 M of file

so a total of about 90 Mb.



It's too late to change the variable reservations...

Patrick,



Suffice it to say that the current version of Lentus does not exhibit the apparent memory leakage I had experienced before. It is rock solid stable even when multitasking with a variety of other programs.



Thanks for checking into my report.
