TZ600 having issues

lately we are having constant disconnect for TZ600. We have done latest firmware update on 4/2/24 and last night as well to latest and greatest. We had 4-5 folks late night testing it and they will get dropped off with one reason "The connection was idle for longer than configured idle timeout". we have "Inactivity Timeout (minutes) = 9999 and SSLVPN Inactivity check = Unchecked.

Question: What does this mean in layman's term "Inactivity Timeout" . Is it no keyboard interaction or no network traffic. We have 1 GM RAM on the device. Is memory leaking?

It is very frustrating . We also have HA device and it switches to that without any reasons and as with volatile memory it looses all logs as well. Looking for suggestions.

Thanks in advance

    There is a certain amount of non-volatile logging done to the tracelogs which you can only find by going to /diag.html. For example, when a firewall reboots unexpectedly, the normal log starts at "Initializing…" but in the trace logs it might say something like "watchdog reboot".

    I should think that unexpected failovers would cause SSLVPN sessions to drop.

    @Praveen I would recommend to open a Support Case to have the Tech Support Team investigate on the issue as there might be some additional tweaks and changes to apply for this: https://www.sonicwall.com/support/contact-support/

    well Fmadia, we have been with support for almost 3-4 weeks and they have tried to put in hotfixes several times and now we had to revert all of them back and we are still having issues.
