  • EA9 Sudden "Not Enough Buffer Memory" Pop Ups

    I have a C-More that has been in service for a couple years that just started doing this. What could be causing this behavior? Everything is working fine, other than this message repeatedly appearing.

    I haven't experienced anything like that yet. Do you have any data logging in the HMI . The SD card might be full. I would need to chech the manual to be sure

      Yes. There are a 5 different strip charts that are logging data. I clear out the SD card every two weeks, so it's never even close to full. Been that way since this unit came online.

        Sounds like you are logging faster than the panel can write. How many pens and how fast are you logging? Ever missing any data?

        You can reduce the logging rate or look into reformatting the SD card with the formatter from SDCard.org. Or maybe a new SD card will help.

          The shortest logging interval is 5 minutes. Never missed a single data point. Now suddenly the unit is refusing FTP connections. Something weird is going on.

            We had a EA9 do this last fall. Turns out that the Panel wasnt seeing the SD Card to write too all of the time (wasnt seated well enough) and would buffer the data. Ended up ejecting the SD Card and installing a new one and the problem was cured.

              Was finally able to get at this unit. quickly setup three buttons to "Copy Log to USB" "Eject USB" then "Delete SD1 Log" I didn't know long each operation would take, so I punched one at a time in that order and walked away for a few minutes. Ended up with what looked like a subset of the files that should be there on the USB stick. After this operation, for the heck of it, I tried to FTP in to the SD card, and all of a sudden FTP was repaired. The fun part is that the SD1 folders were chock full of the files just as I suspected. Not to mention no more buffer memory errors. Copied everything over to my PC, and delted all of the log files on the SD card. We'll see how it goes.

                I have two customers that have suddenly started having this issue. Is FTP the only way to clear the SD1 folders? Or will a panel factory reset do the trick?
