RouterOS 6.44.x pppoe client issue

RouterOS General
1

last working verson:
6.43.12

I have serval device both have the same issue:rb750gr3 rb450gx4 x86
After update RouterOS to 6.44,pppoe client is having a tx drops issue,it happends every 1 minute and drops 2 packets regulary.
When I down grade to 6.43.12 everything is ok and no tx drop issues.
So I’m wondering what is wrong with my router? Config issue or RouterOS issue?

There is also a problem with the 6.44.x branch with Radius and PPPoE - radius timing out after a few days of operation.
This has been reported to Mikrotik with support file via email.

I had the same problem, but it seems like the problem is on CCR (tile) and not on RB100AH (powerpc)

When a client tries to authenticate, it gets a timeout. Restart solved the problem (somethimes), But then userman didnt respond for a few minutes.
Downgraded CCR’s and everything is normal again.

After a few days, the same problem occures on PowerPC too

/ip neighbor discovery-settings
set discover-interface-list=none

dropped packet is discovery packet

Solution is
/ip neighbor discovery-settings
set discover-interface-list= !dynamic

if discovery on a dynamic interface then
every pppoe interface may have Tx Drop
