Memory leak after L2TP enble with RoS7.6

Mon Jan 23, 2023 10:47 am

Has anyone noticed a memory leak when using RouterOS 7.6 with an RB3011.
We have been using this router for a week, for the first day and a half we routed the traffic to the outside via a masquerade rule. Since Tuesday, we have been routing all traffic to our data center via an L2TP tunnel. I can clearly see in the logging that there has been a memory leak since then.

The router gives the following message:
router was rebooted without proper shutdown, probably kernel failure
kernel failure in previous boot
out of memory condition was detected

How can I tell which process is consuming so much memory?

See a similar thing (although not with the same severity) on 7.7 on a hAP ax2 using an L2TP tunnel for Internet access:

It's low bandwidth/throughput which might explain the slow leak.
