TrafficFlow in MikroTik ROS 5.11 - FAIL

RouterOS General
1

I installed 5.11.
If you try to change the cache size (for TrafficFlow) - traffic flow stops working forever.
Reboot - does not help.

I upgrade from 5.8 to 5.11.
If you try to change the cache size (for TrafficFlow) - traffic flow stops working forever.
Downgrade - does not help.
(bug probably “migrate” in Mikrotik*.backup file ?)

P.S. On some servers - ver 5.11 - behaves unstable (Kernel Panic), but 5.8 - work fine too long time…

Do you work TrafficFlow in 5.11 build - if you try to change the cache size?
Try do it …

I wrote in support@mikrotik.com
[Ticket # 2011121366000158]
Sent several supout.rif files and screenshot (error on console)

I am ready to give full remote access to my real server.

I can hope for a solution to the problem, or you do not recognize this problem??

I have the same problem with 5.11 on ESXi host: after reboot, TrafficFlow is not working (zero active flows), after disabling TrafficFlow, RouterOS prints “kernel BUG” with “NULL pointer dereference at 00000004” message on screen (no messages in Log, Terminal, no autosupout…)

some problem with memory allocation?..
