I spent some time digging through the forums and looking at the general AHK function list and didn't find what I was looking for so I figured I'd ask here.

I want to use AHK to monitor RAM usage of a specific program and once it reaches a certain amount of memory to kill/restart it. Has anyone attempted something like this before?

Using the function linked above, you would probably be able to do something like this... You would of course need to setup a timer to constantly check the process' memory usage.

[color=#BF0000]Proc := % GetProcessMemoryInfo( "firefox.exe" )

If (Proc > "400000") {  ; If RAM usage above 400000 K, then execute code...
   ;  Insert code here.
}[/color]

GetProcessMemoryInfo( pname )
{
   Process, Exist, %pname%
   pid := Errorlevel

   ; get process handle
   hProcess := DllCall( "OpenProcess", UInt, 0x10|0x400, Int, false, UInt, pid )

   ; get memory info
   VarSetCapacity( memCounters, 40, 0 )
   DllCall( "psapi.dll\GetProcessMemoryInfo", UInt, hProcess, UInt, &memCounters, UInt, 40 )
   DllCall( "CloseHandle", UInt, hProcess )

   list = cb,PageFaultCount,PeakWorkingSetSize,WorkingSetSize,QuotaPeakPagedPoolUsage
   ,QuotaPagedPoolUsage,QuotaPeakNonPagedPoolUsage,QuotaNonPagedPoolUsage
   ,PagefileUsage,PeakPagefileUsage

   n=0
   Loop, Parse, list, `,
   {
      n+=4
      SetFormat, Float, 0.0 ; round up K
      this := A_Loopfield
      this := NumGet( memCounters, (A_Index = 1 ? 0 : n-4), "UInt") / 1024

      ; omit cb
      If A_Index != 1
         info .= A_Loopfield . ": " . this . " K" . ( A_Loopfield != "" ? "`n" : "" )
   } 

   ; Return "[" . pid . "] " . pname . "`n`n" . info ; for everything
   Return WorkingSetSize := NumGet( memCounters, 12, "UInt" ) / 1024 ; what Task Manager shows
}

Note: I slightly modified the above code from the original source, removing the "K" from the result & deleting block of commented code.

Great, thanks a ton.
