Nstreme dual problem

RouterOS Wireless Networking

Hello, I have a problem with nstreme dual. After some time it stops transmitting data and routerboard needs to be restarted. Disabling and Enabling interfaces (TX, RX, dual) will not help. So I set the watchdog to each other, which it keeps running. But this way the connection restarts randomly, sometimes lasts 2 days, sometimes 2 hours, always reboots at load (not maximum, 20% enough), so in production time. Link otherwise runs well, link rate 144mbit(MIMO 20MHz) in both directions, btest 104mbit UDP and TCP. No load latency 0ms, 10ms at full load in one direction
Connection length 1km. routerbords: 2x RBM33G + 4x R11e-5HnD
firmware and mikrotik version: 6.44.1(both sides)
antennas: 4x JRC-29DD MIMO

Second problem: winbox, when I set something in the dual interface nstreme and click OK, Apply or Cancel, often winbox crashes (closes), generates autosupout.rif but RB keeps running, doesn’t restart. I can reconnect

using 29dbi mimo dishes for 1km is a little bit overkill?
Paste screenshot of wireless status maybe the signal is waay to strong.

Yes it is overkill, I need stable link. And it is stable(ping and speed) until it stop transmitting data. Signal is regulated, TX power on both sides set to 5dBm. RX -46
I try set TX power to 0dBm, 10dBm, 20dBm or default… no change, still stopping transmitting data after some time.
Changing frequencies… no change, still stopping transmitting data after some time. I use 5500-TX and 5700-RX

Now I’m testing the two wireless links with OSPF,TX one link, RX second link, but it’s not as good as nstreme dual.
