SSDR out of memory errors with 64 bit Win 11

Dick Illman

I leave my Flex 6700 on 24x7 to try to be available for remote access. Flex support says that the 32 bit SSDR application runs our of memory because of Windows and .net. The RAM usage starts at about 256MB and over about 36 hours it climbs to 4GB and fails, even without touching the application. The recommended "fix" is to restart SSDR before each operation. How many others are experiencing this unacceptable requirement?

I have run for weeks on 64 bit Windows 11 ( and 10 in the past) and have never gotten over about 800 Mb for the SSDR app ( 4 slices). Most of the ram usage in SSDR is Waterfall buffering. At default WF rates, it takes a less than an hour to reach maximum ram usage. Lowers WF rates will take longer to fill the buffers. Few slices will also limit the max ram buffer usage.

What version of SSDR are your using. What version of Windows and are you running on a 32 bit PC ?

I just checked mine and it has been up for days with 1 or 2 slices. I was at 73M on Windows 10 Pro.

I am running the very latest SSDR version and Windows 11 64 bit. Single slice.

Sadly, it seems that Flex software fixes now take literally years, if ever.
