    Hi All,

    Last two days ago I got a mail telling me to upgrade to software for version 2.
    I did, it was not seamless and needed an extra reboot after but I hope the problem is solved..

    Device Info
    Unit ID 1 2 3 4 5 6
    Unit State Ready Ready
    Hardware Version T1700G-28TQRev2 T1700G-28TQRev2

    Redundant Power Supply Not Support Not Support
    I'll come back when the stack stops again..

    Brian,

    Did it help?
    Was your hardware v2 or v1?

    Thanks

    Just an update

    So after an email chat with TP Link they sent me a different Firmware for the V1 switches saying "a firmware aimed to solve this issue":
    Unit State Ready Ready
    Hardware Version T1700G-28TQRev2 T1700G-28TQRev2
    Firmware Version 2.0.0 Build 20160922 Rel.61374(s) 2.0.0 Build 20160922 Rel.61374(s)
    Power Supply Module Operational Operational
    Redundant Power Supply Not Support Not Support

    However after 8 days the master switch died again with the same issue:
    MEMORY RISING THRESHOLD: Total Memory Utilization is 98%.

    I did briefly try the firmware for V2 on the site (T1700G-28TQ(UN)_V2_170608) however after 3 days the memory on the master switch had already reached 86% so I contacted them once again.


    This time they sent me a new Beta firmware (T1700G-28TQ(UN)_V2_171106_Beta) to address the issue, although now I suspect my issue might not be the same as theirs as the email read:
    This beta firmware is used to solve the problem that the device can't be managed by any ways after logging in the switch frequently by SSH.
    The reason is the memory can't be released timely after the first time SSH login. Gradually, the momory will be run out.

    I never used SSH to log in during the week so this doesn't sound right. But I will try it anyway and keep you all updated.


    Regards.

    I can confirm, that the memory-problem still occures and have nothing todo with ssh.

    we're using a 1700Grev2-Switch for some months and it hangs after 2-3 weeks without any ssh-activity.

    this is still true after an update to the meanwhile available firmware-upgrade (which does not change the version-text, but in boot-menu you can see version change Flash/Software from 1.3.0/1.0.0 to 1.5.0/1.0.1)

    but: it seems that the leak doesn't escalate with lower speed as before and the start-point after boot seems to be less than with old firmware.
    (this can't be verified, since we've no saved logs from the occurences before firmware-update)

    P.S.: sorry for re-formatted quote, but even if this forum seems to work without javascript, it doesn't and first preview killed all linefeeds.

    systems restarted on 2017-12-07 with 72% memory-usage, since 2017-12-11 external logs show 81% up to 85% today, so 2 .. 2,5%-points leak per day
    (reset system today, because of less time these days and won't miss the point of no return (soft- vs. hard-boot)

    I am contacting the Support of TP-Link. Once I get the beta, I will post it here for you guys to try.

    had to reboot the system again on Dec.22 evening with 92% memory usage...
    (20%-points within 9 days)

    today again rebooted with 93% memory usage...
    (21%-points within 10days, even with less traffic due to holidays in office, where the switch is installed)

    after reboot again 72%

    Do you know anything about the firmware? I have this switch and the same memory overflow problem occurs. After about 10 days, it is between 72% and 97% full. and if it does not manage to reboot, the switch is dead. Does anyone test this T1700G-28TQ (UN) _V2_171106_Beta what was mentioned above?

    Hi all

    Here is the beta firmware link for T1700G-28TQ V2: http://static.tp-link.com/2017/20171...71218_Beta.zip

    thanks. (our own support-request at tplink.de only resulted in a link for an old beta-firmware, which we haven't applied)

    we've applied this newer firmware and a day later the memory-usage is still at 72%.

    hopefully there's no other problem...

    we'll see.

    regards

    hi all,

    therefore I've the same issue as abattoir within a configuration of two stacked T1700G-28TQ V1 I Need the Firmware Update for the V1.

    The Memory leak appears in a single Switch configuration also.

    Hopefully there'll be a final stable Firmware for both Versions asap...

    regards

    Hi all,

    therefore I've the same issue within a stacked configuration of two V1 switches I need a link to the appropriate beta version of V1 firmware which is able to prevent the leak of memory.
    I've tried the switch in an unstacked configuration (V1 and V2 hardware) as well and the memory usage increases within about 10 days to a value at over 95%

    I hope there will be a stable release for V1 and V2 switches as soon as possible.

    greetings

    since 19 days has been testing this beta version and the memory is not full any more, it is still on 72% of use
