4 days ago I've updated to the latest firmware version (2.60(AAHK.1)C0) for the GS1900-24E switch.
Seems like there is a serious memory leak... Attach is the memory usage graph for the last 3 months.

    Hi @Gilad

    Could you provide tech support to us so we can check it?
    If you have a privacy concern, you can PM me the tech support.
    You can download tech support on Maintenance > Configuration > Content > Tech Support
    About the attached graph, may I know is it a monitor software?
    Thanks for your cooperation

    Best regards,

    Can't post this file, it contain too much private infomation about the network...
    attached is another graph from today, I'm using SNMP and LibreNMS software to monitor the memory usage.
    The switch restarted itself on Friday evening, if it happens again I'll just downgrade the firmware back to version 2.50.

    Hi @Gilad

    May I know what OIDs you are polling and the polling interval?
    Also, may I know if you could provide the information of "Process Memory" in the tech support to us so we can check it?
    Thanks

    No sure which OID it's using, I'll try to find out.

    Hi @Gilad

    We would like to reproduce the issue
    Therefore, besides the OIDS you are polling, we would like to ask again that could you provide tech support to us by "private message" so we can try to find out the root cause?
    Or, could you remove the private part and send the tech support to us by "private message"?
    Thanks

    Best regards,
    Zyxel_Derrick

    Hi Derrick, I sent you the tech-support file by private message.

    We will try to reproduce the issue and if there is any update will let you know asap

    Thanks you Derrick.

    CPU and memory usage in the last 3 days. Seems like the GS1900-24E SNMP process can't even return the values... I wanted to generate another tech-support file, but I can't even access the web GUI. Going back to firmware version 2.50.
