Hi all:
       I'm using aSubRecord to handle an image(a waveform record with size 640*480),
       After some process,the treated data has been output to another waveform record.
       However when this IOC is running, the “top” command tell me the IOC consume about
       1.5G memory(my pc has 2G memory),and only one client(an edm client) can connect 
       to it and display the image which has been treated. Even an epics gateway is running
       as a middle layer between  IOC and client,the problem is still exist.

My asubrecord db like this:
record(aSub,"asub")
{
    field(INAM,"myAsubInit")
    field(SNAM,"myAsubProcess1")
    field(FTA,"UCHAR")
    field(NOA,"307200")
    field(INPA,"image0 CA")

    field(FTVB,"UCHAR")
    field(NOVB,"307200")
    field(OUTB,"treatedimage CA")
}
record(waveform,"treatedimage")
{
field(DTYP,"Soft Channel")
field(FTVL,"UCHAR")
field(NELM,"307200")
}

in the process function  myAsubProcess1,even if I am doing just a simple work(set the waveform pv to 
a const data),the problem has no change. 

Is there some suggestions? Thanks for you help.
                                                                wantianmin
