MLAT Problem stopped at my location In The Netherlands at 15:58Z on one system.
Other system last reported it at 09:05Z today
Both systems are Raspberry Pi’s.
Two other systems, based on Orange Pi 2+E board running armbian haven’t had any MLAT issues since the upgrade 24 hrs ago.
All 4 feeders are on the same internetconnection.
So the network change had a positive effect for me.
I’m running a PiZero, and the problem (clock unstable) seems to be gone for about an hour now by confuguring slow-cpu=no.
Are you guys seeing the issue now? The issue seems to be improving on the server side.
Fingers crossed its all sorted no more udp error
I haven’t had a single warning for a bit now, thank you for fixing this 
As of right now, the errors are gone on my side.
Thanks for fixing the issue
It does not appear any longer on my Raspberry with Piaware 6.0 installed
The MTU change notification seem to be not related to Piaware 6
I have connected my Jetvision device which still runs Piaware 5 and the message is the same.
But it does not lose any MLAT packets, so i think it’s good to ignore it

My sites, updated to 6.0, started to show MLAT issues this morning.
The only one that still works is a FlightFeeder 9.2~bpo8+1 (I guess that’s the old version of software?).
The other FlightFeeder 9.2~bpo9+1 (UAT978) has the newer version (?) and shows errors.
For me the issues are gone. Only the MTU size changes every 10 Minutes between 1492 and 1476.
But no further loss of MLAT data
These are the same version, just built for different distributions.
No recent FlightFeeder upgrades. You’re seeing something else, not a software change.
Thanks, I wasn’t sure, hence the (?).
The MLAT issue is fixed now.
