#SimBridge using more than 10gig of memory

Using latest experimental, as said above, I see that SImbridge is using more memory than the sim. Just using it for the terrain radar, memory usage stays high even when terrain off. Not sure if this is the right place...

Got the same problem with develpment version. Simbridge is uising 5 to 12 GB ram

There's a bug with Simbridge and the radar map, if you find it eats all your RAM memory, stop using it until it gets fixed

I think this could be the reason for my rare but recent CTDs. They only happen on the 32N and the A321N from Horizon simulations AND they happen around the time before TOD and both times it was a flight longer than 3 hours. Since the A321N is based on an older version of the FBW I was looking for a common denominator... and here it is: SimBridge usage. I'm almost sure it's a memory leak with SimBridge that crashes my sim once enough time has passed.

#

I have no CTDs with any other aircraft (Fenix, PMDG, CRJ, ATR etc.), by the way

#

is this being acknowledged by the devs? This could very well explain many of the reported CTDs over in the main chat

Can you provide the routes you flew when this happens? We are not able to reproduce that reliably so any hints would help getting this resolved 👍

I had it once in the Headwind from WSSS to WIII just before intercepting the ILS I had a CTD with the message: run out of memory and on task manager I saw that simbridge used like 20Gig.

And another question: was the Terrain Display on when this happened?

ANIT7F ANITO B470 BUNIK BUNI2H ILS25R via PIROK

#

AMD-GPU (5700XT) and Terrain was on

#

i think it chrashed around PIROK

Hi, sure, so one CTD was from EPLB to EGGW with the following route: ARGI1J ARGIX T709 KOTEK BAREX NAROX KUMER WRB NOGRO M40 RINIS RINI1N. The other CTD was GCTS to EGGW with the following route: VAST8F VASTO UN858 AKUDA BARDI UN873 DELOG FUJTI IDNUN ATGEB DIKRO UM185 TELTU TELT1N

I'm quite sure I didn't use terrain radar at all at the flight from EPLB (because Poland is flat), as for Tenerife I might have used it. Simbridge was connected in both cases.

Is this fixed and all? Haven't been using SimBridge for the last 6 months because I fear CTDs.

Some changes have been made but we cannot 100% guarantee the issue is fixed as the cause and repro was unknown unfortunately. I personally have never encountered a extreme high usage (8+ GB) and I think we also got no new reports. I think it’s best you try and observe a bit.. if it occurs again let us know, then we need to change something in the architecture.

This is still an issue. I an new here, just cam across this. looked at simbridge memeory and saw that is grown to 17G! killed it and restarted. Please let me know if you need to help debug by running any logging or running an instrumented version.

this cause my 32G of RAM to get exhausted and then for it to swap to my NVME, which i have narrowed to hesitations on msfs. turning off ND terrain is my asnwer for now, i.e. only running it when I need and not leaving it on all the time.

#

also wrote a powershell script to relaunch it after 18G of ram, and there is less than 5G for RAM free, this seems to be working well for me.

$procName = "fbw-simbridge"
$RAMLimit = 18GB
$FREELimit = 5GB


while ($true) {
    $proc = Get-Process $procName -ea 0
    if ($proc -ne $null) {
         if ($proc.WorkingSet64 -gt $RAMLimit) {
        $free = get-ciminstance Win32_OperatingSystem | % FreePhysicalMemory
            if ($free*1024 -lt $FREELimit) {
           Write-Host "killing fbw-simbridge larger than $RAMLimit and free mem less than $free*1024"
               Stop-Process $proc -Force
               Start-Process E:\FlightSim2020\Community\flybywire-externaltools-simbridge\fbw-simbridge.exe  -ArgumentList "-hide"
            }
    }
    }
    Start-Sleep -s 30
}

will help with those overnight flights i leave the ND terrain on by mistake.

Fixed??

Set it and forget it, there’s a YouTube video out there on how to use it
